I am one of those who today will buy a coin that will become more expensive tomorrow.
There is no need to say "Buy HBC for $ 0.3", because here are those who have long bought for $ 1, $ 2, $ 5 ... and see how investments lose their value.
See above

And if you know for sure what coin will become more expensive tomorrow go and buy it! What the problem?

no one knows what will be more expensive ... maybe tomorrow I will wake up and a 0.1 coin .. and not 0.3 and certainly not 10
