If you have a look at Coinmarketcap you will find out that there are thousands of coins and tokens listed over them but do you think there is any potential coin over there that can possibly give your desired profits? But if you funds then go for top altcoins like ETH or BNB because of Binance growth it can give return otherwise there are pump dump coins in which you can make short term profit if invested timely.
Indeed Big altcoins would be a better option if you are looking for a more consistent investment or having less risk involvement. But if you are willing to go down for the profit, smaller names would be a good option BUT you need to know which is which. New tokens has higher rate of increase over big names in this industry but since we are talking about profit, bigger risk would be present. The market prices of new tokens or altcoins has a higher volatility in terms of their market prices. Indeed it could generate bigger profit but that would also mean that there is a higher tendency for an investor to lose if he'd come across or be picking wrong altcoins.On my end, I prefer long term investment on altcoins such as with tokens with established communities (BNB, ETH, XRP and the likes), while waiting for bullish trend.
