I think life would be much simpler for everyone if people consciously chose the amounts of money they invest in this market.

I don't think anyone would be too upset if they didn't know which ALTcoin wouldn't have increased if they put $10 into it.
Because you can live peacefully without that $10.
The example is extreme, but you understand the idea.
The amounts of money invested => the stress generated, the frustration, sadness, nerves.
It all comes down to sums.
The mindset should always be: How much money could I lose?
no...
How much money could I make.
