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.
WTF, don't do that. ICO are very risky moreover with long term investment. I suggest you to invest in ETH or split in some Stong Coin Like NEO, ADA, etc.
with the longer holding Altcoin will be even greater profits that are able to obtain.
so I strongly recommend to use Altcoin which has a development far more rapidly than other Altcoin such as Cardano.
