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.
you take the right steps, for beginners it is still too risky to invest in ico. because our reason is sometimes just just feelin. so we don't know whether ico will be successful or not. so I have good long-term altcoin advice, at least during 2019, which will go up, namely ripple (XRP) and cardano (ADA).
