If you want to hold on for a long time, then I suggest you invest in several ICO projects, so long-term holding could have a surprising return. I recommend you to join these ICO.

Special thanks to you. I will research it. Before this time, i play ICO but i lost a little money. I dont believe in ICO until this time.
Yes its better to make your own research because some suggestion will is not totally good. If they suggest you some altcoin you need to search it and choose good and i know you said you are not believe in ICO this time but you need to try and make research some ICO because not all ICO is scam.
