Grin is one of the coins that I am very optimistic about increasing in price and becoming more popular in this space in the future.
However, keep in mind that whatever we all talk about in terms like GEM it sounds like venture capital, if you haven't done your due diligence don't get your hopes up. this. Basically some of the coins that I follow still give me a positive feeling about it going forward but if it doesn't, that's okay too.
