And it is not even question to me personally. I buy cryptocurrency for all my money and re-invest ALMOST all my profits into another, most promising coins.
this is a bad move though. i also believe in the future of cryptocurrencies and have a lot of investment in bitcoin but only bitcoin. but i still am not going to invest all or almost all my money and profit in it. bitcoin is still volatile and very young, all the potentials that it has doesn't change the fact that it also has risks. and when there is risk you have to manage it properly.
