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 not always profitable to invest in ico, sometimes new coin from ico is only for dump by investors and it makes other who are plan to hold it long term lose so much money. I do recommend you to hold eth, eos, pundi x , matrix ai and dentacoin.
