Just like me and I also have assets that are under the top 50, some are even not in the top 100 list. It does look doubtful, but there are clear considerations that are our fundamental reasons for holding it and believe it will be an investment that can provide profits.
It's totally legit that there are some people who still investing in cryptocurrency that under the top 50. Even they are under the top 50 cryptocurrency some of them have great potential in the future and they even give a big profit that you will never expect to happen. Actually, I don't have any coin that under the top 50 cryptocurrencies and I usually spent my money on Bitcoin, Ethreum, and Ripple. Then, until now I still undecided if I'm going to risk my money in Litecoin. We should always look for a coin that has good development because those projects will totally survive in the future and trust me, the top-performing coins today will definitely bring you an good income on this coming bull run.
i myself have many tokens from projects beyond the top100 or even beyond an exchange listing.
but i wouldn't actively search for them. you can get them via airdrop and bounty.
if you plan to invest in fiat then you better look at the top10 to be on the safe side.
Most of the token from bounty and airdrop are worthless or basically a "shitcoin" but not all of them because there is still a bounty project that worth it but you will spend a lot of time to find it. The top 10 cryptocurrency is totally suitable for a long investment and that's why it is also a reason why some people intend to invest their fiat to those cryptocurrencies.
