I have won a lot in the past months
BTCBut in the last month I suffered heavy losses

What do my trading friends tell me to go beyond this difficult period?
Ups and downs! The same we have it in real life, it is also there in the crypto market. This is the down period and a lot of coins are taking a huge dip, so you have to be careful in the market, better to either relax and see how things turn out in coming days or you are really sure of the trend of the market you are getting into. However, it is just a matter of time before things changed back to normal.
