For me, i do not think everyone failed altcoins, instead altcoins failed us.
A new project will show up, introduce a product, request for crowdfunding via ieo or ico, we buy in thousands as investors, Then token lists, price soars 2 times ieo price, Then team dumps, leaving investors to their faith.
Altcoins will refuse to launch their product, instead, delay announcement until they dump all and go awol.
I am a investor, i do not invest in crypto currency to be compassionate, but to take profits. Altcoins should so seriousness and put their all to make projects a success.
Altcoins rely on us all, as an investor, community member, bounty hunters, but give little in return.
It has to be a fair affair i suppose.
I understand where you are heading to. But not all altcoin are to be expected to do well, don't jump into any altcoin blindly you can limit your altcoin investment, or if possible focus on one.
