Hard to say for now, since market is not going to good condition, in long term, if u believe in their team and the product they are making.
Every participant in this market has great trust in big projects. I think in the past few months the Cryptocurrency market has received a lot of bad news and a lot of people are protesting about this market, which is very influential because the market is still very new and just a little bit bad news can also make Bitcoin lose a lot in a day. Personally, I always advise people to invest in Bitcoin as this is probably the biggest market in the future
