I have few project that I really enjoy.
Monero, Ethereum and Raiden Network above all.
I don't have a lot of money so my investment will be not so important for the teams.
I don't really care for profit considering that I have only 100/200$.
So what is better?
Support a single crypto with all I have or separate on every crypto I like?
Depends on how aggressive you want to be with your selection to be honest. If you want to diversify and not have one company take the reigns then spilt it up but if you want to be aggressive and have the best chance for
reward then dont diversify pick one and slap it down. Really depends on your style and what kind of risk you want to undertake.
