With the recent changes in BTC price, altcoin is getting weaker against BTC, so, this is a good time to pick and fill the bag. Another important part is, after BTC bullrun, once BTC get stable, altcoin follow the bullish trend.
Is it right decision to pick some more altcoin?
In my opinion this is the right decision. In connection with the decrease in the price of altcoins, you need to take advantage of this situation to obtain maximum benefits in the future. But don't forget to be careful and attentive and don't neglect the use of stop losses to protect your funds from unforeseen situations.
