I recently joined usi tech with a small amount. The bitcoin aspect has not been there for 6 years but the company itself is. But i believe it will be there for quite a while. But for now they have proven to be a good company even with all the bitcoin ups lately.

I suggest to do a youtube search on usi tech and read the information pages, they have a lot of videos and webinars to see/follow so it will give you an idea. Dont blindly follow others, find out your self and then make the dicision of joining or not. Also make a strategy before you start and keep in mind that nothing lasts for ever. Goodluck !
