If anything at all I want to spend my coins, not sell them, I am not a coin collector. I bought some pizza and it tasted extra good, just like the coffee of acquafredda Smiley

If the price goes up, it would mean I can spend even more bitcoin and buy more stuff, hooray for consumerism!Also you can invest on btc to bch at good exchange rates now.

It is the dawn of bitcoin, still, so the most people can do is hold and hope or if they are in it for a quick buck buy and sell to make some more.

I don't know about ya'll but I'm not really looking forward to this so called Libra coin. First off, it's not even a cryptocurrency. For a crypto to be one, the underlining feature is to be decentralised, which, Libra clearly isn't. Second off, it needs to be peer-to-peer, which again, Libra isn't. And if some articles are to be believed, we can't even use Libra like a normal crypto! Just use it in the fb or messenger app, idk.
I could go on and on, but anyways

I've also heard about bitcoin wallets offline, but I don't really understand how it works, and I've heard that offline bitcoin wallets are very safe.

Yes, indeed they are! You won't find any safer wallet than these offline wallets. The reason lies behind this simple fact:
Online wallets, most of the time, store your private keys. These private keys are actually stored on an online server (which you can imagine how safe it'll be).
The thing with offline wallets is that they store your private keys and don't require to be connected to the internet all the time (for hardware wallets). (For paper wallets, it'll never be connected as it's literally a piece of paper).
As most of the hacks and malware and viruses are transferred over the internet, you won't have to worry about them infecting your offline wallets.

Bitcoin is the king of cryptocurrency which is rulling on the market everytime.I don't think altcoins will replace btc.

In recent times, IOTA has been quite stable and doesn't seem to be affected by the bullish surge of bitcoin and the surge in altcoins as well. But it's price is deemed to increase, with the iota price prediction being $4 USD by the end of 2019.

Even if Stellar might be doing well, it doesn't seem like it'll jump from rank 10 to rank 5 within a month. I'm not denying the possibility, just saying that for that to happen, it will take a lot more than just a month. That said, it all depends on Stellar's performance and if the xlm price prediction is to be followed, then it might reach till $0.66 USD by the end of 2019.

ASICs are kind of centralising the mining of cryptocurrencies. But, luckily Monero steers clear of it. For monero mining software like XMR Stak, MinerGate, Monero Spelunker, CC Miner are used. This is what makes Monero so special, apart from its other characteristics.

With the approaching Litecoin halving, if anything, the price will just soar higher and higher. And that's expected. Currently, the price is hovering at $140 USD and if the litecoin price prediction is to be followed, it may even reach till $230 by the end of this year.
