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?
maybe exactly so but you have to choose a good altcoin that has the potential to be not an altcoin in the future when it's the right time to save a good altcoin with prices that haven't gone up too much like xlm,xrp
