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?
That's the tricky part and if you are already aware of what could be the results then it would be a wise move then. In most cases, after the bull run, then there's a temporary stable, altcoins started to also increased. As long as you continue to monitor in the market then definitely you could get some good coin to buy which it has the potential to increased.
