I don’t even believe that having Alticoins is diversification of portfolio, because most of these top Alticoins that are regarded strong usually follow the bitcoin trend, so why bother to invest in them when I can just earn same profit from a coin that is not centralized.
Another thing why there are some people are being lured to buy altcoins instead of Bitcoin is because of the ROI they can see versus Bitcoin.
Exactly Alticoins have the potential to increase in short term than bitcoin, because this is the only way its developers can lure investors into it. The same way it has high return it also dumps in same way, and that is why it is mostly advice to treat them as pump and dump coins and not assets for investment.
