Bear market was ended by this season,so i think the reason behind this is the thing that happened in bitcoin because its price was totally dumped in the past month so for me most of altcoins was totally affected on what happen in bitcoin,but now the bear market was end up and this is the new beginning in crypto.
Now it's time to invest because the market looks good and continues to increase, I'm sure that this year we can get big profits by continuing to buy, of course buying coins that have a good reputation for profit.
