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.
It is going to be difficult for any coin that is ranked that low to make it big during the next bull run, and this is because when it finally happens a bunch of new coins will appear that will promote themselves heavily over the many social media websites that exist, and any money that could have been gone towards those coins will simply go to other projects that at the time may seem to be more fresh and attractive, while a great deal of the coins that were released before the bull run simply get forgotten and never produce the results their investors expected.
thats true, with always changing market of altcoin it just simply hard to keep holding one coin that hasn't grown significantly over the course of the year just to wait it out to gain the capital that it "deserve" in which our opinion are sometime heavily biased.
its just better to invest in newer coin altogether with massive growing community to get that share of pie, because for these newer altcoin gaining increase in value is definitely easier than those old coins that are simply stuck and can't grow.
therefore its just better idea to just ditch those old coins and move on.
