I understand you perfectly. To the flow of crypto enthusiasts and fans of Bitcoin, I also stuck a very long time ago. More than 5 years !! I stood aside, just read the forum, and admired what awaits us in the future.
But now I am terribly disappointed that everything began to stop developing ...
There is a bunch of garbage altcoins ....
I am a sincere fan of Bitcoin, and of course I identified for myself a dozen projects that also make sense.
And I completely agree with the author, for all this time I came to the same conclusion -
you need to invest exactly as much as you are willing to lose. But let's not forget to support the development of cryptocurrency

The appearance of so many altcoins was inevitable, something similar to this has happened in the past, when the dot com bubble happened there were many good ideas that appeared and those are the technological giants of today but for every one of those businesses there were hundreds of ideas that never worked and made people lost all their money so this is nothing new.
