Here is a good source to decide which altcoin to invest in. I would never buy a dead altcoin with no development except Doge. Doge is unique and will be successful without much development.

- Verge
- Holochain
- Bitcoin Private
- Pundi X
- Poet
- Decentraland (MANA)
I dont know why some people experiment on shitcoins even if they know that they have a better peofit on top coins. If you want to have profit,invest on the coins that are obviously moving and will benefit you on the future.
