While most of the people are awaiting the massive bull run like in 2017 winter again, it will not be a case again.  While I wish BTC to go into new ATH before the end of this year, I think that reaching 13K to 14K gradually testing every pivotal point before the end of this year is more realistic and more healthy for the market too.

I am bullish in Bitcoin doesn't mean I am expecting parabolic run every time bulls ticks on.  The 20K level that bitcoin reached last year was a enormous craze and mostly FOMO and/or may be manipulation which will not happen again and again.  So, the people who bought at 20K will have to wait for few more years for that massive bull run to return, that's why they always says "patience is key".

The bitcoin price fell free, losing nearly $ 14,000 in value since the peak of 2017. But while cryptocurrency hovered around this year's lows, a new $ 300 million fund dedicated to the crypto market has given investors fresh optimism. The cryptocurrency market was further encouraged this week by news that Facebook reversed its decision to ban ads for bitcoins and other virtual currencies.

This move once again sparked rumors that Facebook is planning a major acquisition in space, or even potentially cryptocurrency itself. Facebook CEO Mark Zuckerberg said in early 2018 that he plans to "go deeper" with cryptocurrency technology - which offers more than 2 billion users worldwide - launched the blockchain exploration group. Other analysts said that the lifting of Facebook's ban will help reverse the price trend of bitcoin and other cryptocurrencies.

"The crypto market has been in bear territory over the last week or so," Nigel Green, founder and CEO of financial services firm deVere Group, said in a statement to The Independent.

"Facebook's step can be expected to help take it back towards the bulls... Savvy investors are looking at the bigger picture."

Looking at the 12-month price history of bitcoin, the cryptocurrency's current value still represents a 260 per cent increase year-on-year.

Is there anything that can destroy bitcoin
Can we have anything that make bitcoin to become history in crypto space world?

bit coin should be made mandatory in all over the world, to purchase anything, it should be available on all online apps, it is safe and security.

Which wallet are you using and why are you using it?
(I know wallets are safer, but if the price drop and you want to sell your coins, wouldn't it be inconvenient if your coins are in your personal wallet?)

I know there was some company experimenting with paper notes to help people who have not internet use BTC.

Anyhow this is an interesting thought. Do you think that it would be possible to put not exactly BTC into a paper note but any crypto in some what of a denomination in a paper note. eg hardware

more less it could be used for people who have no access to internet have spending power, where the paper notes would have  bar code scanner code on it, that they take to someone else for buying goods and services.

Your thoughts on this idea, could be used in whole numbers of a type of crypto if the numbers meet up to a certain standard, as not to correspond to a FIAT system but be entirely in Crypto?

your thoughts? pros and cons to this concept.?

why it could work ? or why it would not work?

Those who want to believe in BTC at all cost, should avoid this topic.
To help some people, who started to think about the core concept of bitcoin, my judgement is:

1) The blockchain part or "mining" in case of BTC is a special kind of scam. For getting a coin You must invest into electricity and computing power. In return You get VERY little chance to be awarded with a coin. This chance is so small, it is mathematically ridiculous, but in practise. ZERO! Nada, ничто, nichts... What kind of decent money is that, that everyone can apply by spending real money but only few of many millions are actually given by basis of pure luck?

2) The coin part of BTC is a monetary fraud. Although people make transactions voluntarely, they are cheated with the very core concept of BTC. While blockchaining may have some usage as a concept as well as cryptocurrency, it does still not mean that BTC is legit.

Before You attack my opion, try to give logical answer to these questions:

a) why is BTC quantity limited with 21 millions? What limits it?
b) what is the point of decentralised money, if its so volatile, that rate would drop 75% in 6 months (or grows by the same)? this is called a hyperinflation.
c) why is blockchain technology better in 99,99% of transactions, than regular private/public key technology?
d) do You really understand, what is private/public key crypto and blockchain in its core, or they just sound cool?
e) if BTC had at more or less decent chance to boom again, why dont all the richest investors in world buy it?

Maybe it wasnt planned so, but BTC is the most genious scam in the history.

Previous doesnt mean, You absolutely can not make any money in it. The same goes for ponzis and pyramids. If You go in or out right time, You will earn and at some cases earn well!
