It has been 3 years since I first got into Bitcoin, and ever since I began using it, I've became fascinated by its underlying technology that could change our daily lives as time goes by.
Nevertheless, it is to say that while I know how to use Bitcoin, as well as how it works, there are still some concepts about the blockchain that I would need to understand, to help become a blockchain expert in the future.
So, I would like to know your recommendations or advice, that would help me get started into this field. If you happen to know of any good resource, or source of information that will help me accomplish this task, I would greatly appreciate if you would share it with me.

I've heard a lot of people say, there are lots of coins that are good to buy, but I want to know, what coins are the best for me to buy?

Blockchain Technology was driven to fame by its application on Bitcoin Gold due to its encryption that has been considered hacker proof. Bitcoin has been used as a reference to its success, providing a secure network for users.
The question however is, can blockchain succeed without bitcoin?

if i see lately there are lots of altcoins popping up, especially in the digital world and whether for the next few years the function of real money itself will be eroded by the presence of virtual payment equipment ...? I had time to think whether in the next few years we would be making virtual money payments ...?

Despite severe falls, crypto always seems to make a comeback. There are certain articles that say crypto will die a sudden death.
But apart from these negative speculations, I always see investments pooling in and startups encouraging and coming forward to use crypto.
What is your take? I haven't personally gained too much off late but I always shake it off as part of learning the trade.
Hoping to get some positive vibes that motivate me.

I have a friend who is interested in getting into bitcoins but he does not have a lot of savings or any major investments. He also has a lot of debts to pay and has an average wage job with a family of 4 to raise. When we were talking yesterday, I thought: who really would benefit the most from investing in bitcoin or cryptocurrency? Can those who are like my friend get into bitcoin even though he has no major investment? Or is bitcoin only for those who can afford it?

With the recent decrease in value of Bitcoin, the value of almost all the altcoins dropped too.
Now BTC is rising again and so are the altcoins.
I am thinking that if Bitcoin ever crashes, I mean completely drops to a very low value and when doesn't increase anymore.

Then the altcoins are going to drop too and won't have a high value anymore too, which means the cryptocurrency world will die.

Is my statement just nonsense or can it be correct?
I'm curious of what you all think will happen to the altcoins if BTC crashes for real.

What is the basic reason of bitcoin that it's price goes to suddenly down so guys please I need reason if anyone know. Thanks
