As for me 30% of my assets is what I'm willing to take risks with, this is the exact amount I can afford to lose, I know bitcoin is very strong and also have a better future than other valuable assets out there but we can't be too sure what tomorrow may bring, one have to be cautious
If you are capable of sparing that amount of percentage then you can keep your assets for longer time, 30% is really high and once
you successfully holds your investment that might bring you a better future ahead, Bitcoin already proved that holding for longer time
frame might provide a much higher appreciation.
