In my opinion, it's not a bad time to invest now. Some coins are really very cheap now and I believe the market will recover in the near future.
I want to invest some project such as, Tezos, Cardano, NEM, Dash, Maker, NPXS, Lisk, OmiseGO, Zilliqa, Komodo, Status, Waltonchain, Elastos.
It that a good idea to do it now? Any comments are welcome
I dont have enough knowledge about this all altcoins that you mentioned. But I also like Cardano, Nem, zilliqa very much and I've made big investment espeically on cardano project. They have great future.
