Investing in crypto is not meant for you if you are afraid of losing money, we are in a near market where it will take a long time for bulls to come back so now is the best time to buy some and hold but still you must be strong at heart to keep holding, probably this bear market will be here for 1 and half years, if you aren't prepare for this then do not buy coins right now.
Are you talking about new projects or those already on the market? OP is asking whether to invest in a new project at this point?
In my opinion, this is not the right time to invest in new projects, they are very risky. We should focus on bitcoin and top coins because their resilience is higher than others. Investing in new projects is not bad but we should look at the market situation to invest if this is a bull cycle then investment will be more suitable.
