There are tons of altcoins. You should be careful while investing. I suggest to do your own research before investing rather than relying on others suggestion. I've recently lost some money because of some pump and dump groups so be careful.
Pump groups will just be a trap for everyone, because they also want money for themselves, so don't trust such groups too much because they won't care who will be the next victim, so it's always advisable to research very carefully on every investment that we want to run.
