There are quite a number of coins out there from the airdrops, but all that matters is the value one can get from them, one thing for certain is that there are some coins out there worth holding on to,. While other are better off sold , it all depends on the. Quality of the coin
Yes, not all coins are the same, there are several coins that only become leaves in the wallet, but there are coins that are very good to hold. I think that depends on the product and team, if the product is good and the team is serious in developing the project, the coin will be very valuable and vice versa. Nowadays there are so many devs who only make their own profits so we have to be careful when choosing a project or coin.
