I invest several crypto projects back in 2017 and got a huge return on the last bull run. I would probably say that in this bear market I saw many scammy ICO that clearly the people behind it have no experience what soever in this space, but I also some potential ICO project that success launch their project and even the ROI from ICO is quite huge. Always double check the team and vision that the project offer will help you dodge scam ICO.
