Few coins that you mentioned on your list are risky to invest in. Would be better to put most of your money in bitcoin and ethereum. Maybe a little in lite coin. But be careful with the rest of the coins. And yeah, now is the perfect time to invest. The price is low, if it goes lower, invest even more.
If I'm not, WPP energy was a successful project, but these projects already cheated tokens holders. Definitely don't buy any WPP tokens, today or tomorrow it will turn out a scam project. As my experience, they technically switch to BSC during Ethereum high transaction cost. Dev did it because they wanted to burn some low holders tokens.
I don't think a "successful" project would cheat "token holders". If they really did, then they are scam project waiting to screw over rest of their investors (dump and exit). So stay away from them.
