If I have 3 ETH, I will do these works.
1. I will Invest 1.5 ETH in a good ICO
2. The rest of it I will Buy tokens
This is my choice. These two are very good for making good profits. If I don't meet a good ICO or good tokens, then I will hold my 3 ETH for 2/3 years. Actually at this time is very good to HOLD because the ETH price is at very low.
