You can research yourself because I think we do not have the right coin list that can be good to buy. That is because many coins have the same chance to be the potential coins that can increase. If we suggest you take a look at one or more coins, that will not always give you a chance to profit because we have a different reason to buy the coin. But if you want to hold it for a long time, you can buy bitcoin and hold it. The only bitcoin will give you the biggest profit than the altcoin.
well I am not here to really get a list of the next 1000x coins (that would be great btw:))
I have my own list and candidates, but sometimes comparing with other users may be productive....you could notice something you missed at first.
Maybe you can take a look at the top 30 coins list. In that list, you need to analyze the low coin price less than $20-$30, so you have a limited coin to analyze, which can help you reduce your spending time searching for the coin. I am sure you will see a potential coin you can buy while the price does not yet increase. After you can get the right coin, you do not have to use too big money as we do not know what coin will increase. But it is great if you already have your own list and candidates, so I hope all of your coins can grow in the next altcoin season.
