Well, there are some poocoins that are only meant to be around for a very short period of time just for the purpose of making huge profits out of it by the owners of such Coin after a dip and thy just dump itVery interesting what you describe about luno, I have read information about this wallet and apparently it meets many requirements that others do not. I think that the case of the CELO wallet offers a different alternative to other wallets, it is a question of time and verify if it is maintained or disappears.
There are indeed many tokens in existence today, and we cannot review them all. Personally I have too few to evaluate, so I discard and add new ones. I hope as you describe that CELO is not a ppoocoi
