there's no need to change the original set up yet adding extra spare funds is much better, cryptocurrency still on it's bearish trend
though some sparks are showing but not enough for the bull to sustain it's momentum, for most traders bitcoin still the reliable investment inside
this market.
While allocating spare money for new coins to invest, take your time reviewing those project which is included from top 20 around CMC.
Bitcoin is actually still the king now when it comes to the most reliable crypto currency to invest in but do you think using Coin market cap top list to determine which project to invest in is really reliable.
Other than altcoins, Ethereum and Litecoin, I have seen a lot of coins tat where at the top 20 in the market sudden disappear from the top list leaving to the site user to start looking for the number it dropped to, so I think the best way is to study about a particular coins of interest thoroughly before investing in as you also suggest.
