I know this is opinion-related topic and I shouldn't consider your answer as financial advice. Anyway I'd like to see what you think about it and what you would do. Even better, you could reason why you think this way.
This is a good start.
Now, you probably know that Bitcoin (and altcoins) prices variation/volatility is big. This makes Bitcoin an interesting investment if you have money you afford to lose, but not "safe" as "savings account".
Bitcoin price, on long term, should grow a lot. But there are big falls too and there's a risk that in the moment you need your money the price is lower than when you bought.
Of course, you can be lucky and get rich by buying Bitcoin and catching the best moment to sell. You or your kids..
Edit: I would probably buy Euro, Bitcoin and maybe gold too (although I'm not sure it makes sense for 2-400$)
People should really think off this way rather than believing that they would be rich when they do go all in with Bitcoin or
any other crypto.
Usually people do have this kind of mindset which its a result for those who do directly engage or involved without any proper research
and verification on what these things is all about.
I wont risk up my entire life savings on Bitcoin.Yes, we know the potential but nothing beats when you do save up money on traditional storages like banks.
