On those altcoins, Dogecoin could have a 100% increase because after Bitcoin had a 10% increase during the start of April, Dogecoin spiked up to almost 50% in terms of BTC price and nearly 100% in USD price.
what if you choose all the coins. and set the percentage. example. 50% for BTC, 25% for ETH and 25% for LTC. 3 coins will give you many benefits. 100%, 200%, or 300% at the end of the year. But it seems that the development of LTC will be slow.
Splitting his investment won't only give him benefits at the same time it could minimize his profits because some altcoins could underperform too.
