I have two altcoin whose market cap is still low and of course they are still ranked 2k+ in coinmarketcap, so there is a possibility that when the bullrun occurs and the altcoin that I recommend is successful, then the profit that can be obtained is more than 100x or even 1000x, but of course you also need to 'DYOR' before investing in altcoins that I recommend and altcoin that I recommend are Bitrock & ETE.
the thing with these altcoin sub 2k rank is that they could pretty well get ignored once the altcoin that are released in bullrun season coming out.
therefore it advised to just invest small amount and there are no guarantee that they will indeed follow the trend, they could pretty much just don't follow the trend of bullrun and lose value.
