So how to spot these coins before they get popular or are listed on big exchanges and are purchaseable at decentrilised exchanges?
I think right now there are a lot of groups of experts who are always on the hunt for gems. They bring together professionals, experience and expertise to find the right project. I was fortunate to have known Sovryn from bitcointalk first, and BCW. Compared to all the IDO launch projects or some other gamefi thing, Sov is probably showing a macro vision and meaning along the way. I think it will be a super good project for a defi for bitcoin, it will be uptrend for near future after Taproot.
Currently, Social media is doing some good for gem projects because few influencers are giving all updates related to good projects with teams and use case, which is very helpful. But main thing is still we need some good work from ourselves for having good information about project which is good for investment.
First check about team of developers who is in and what is their record in past about their work because it's very important then check use case is good or have any good impact in future because It's also very important if you are not able to check these things surely It's going to create problems for you and your investments. Sometimes they have white paper which is copied pasted which is never been helpful for any investor. So going through with some of all things is surely good for anyone.
