Well my first ICO that I invested was Bob's repair and lucky that I profited it was 2018. When the market was crashing down I never invested ICO anymore because many projects were failed and some turned to scam.
I am very fortunate to have invested in a lot of big ICO projects like Bancor, Adex, AppCoin and these are all projects that helped me to earn very high profits during that time. However, these coins are no longer the same as before and no one cares so these coins are currently at a very bad price. Now it seems that IEO is getting more interesting because any IEO project is guaranteed liquidity if it is a potential project.
