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.
Most people enter the cryptocurrency market for the purpose of investing in order to make a profit, there are many who are not even interested in what blockchian technology is.
For that reason they became Fomo with news and could buy any altcoins introduced.
Personally, I paid for the same case, I bought a lot of coins from new projects. There are some projects that are really profitable but most often end up with a pile of trash.
At the moment I only focus on investing in Bitcoin and the coins in the top 20 largest currencies on the market.
