Never needed a chart in my life for the OTC and crypto and never will. Made a ton last year December 2020 through February 2021 just like everyone else, as EVERTHING went up. Even deadwood. The more plays one had, the more they made. Had zero to do with charting. Mine is all in Roth IRAs. Paid zero taxes as well.
I just started a new crypto board to talk about cryptos with over 16,000+ coins out there now. Come join us to learn how to trade them. Micro cryptos are where big bucks can be made, like the OTC. Just search Micro Alt Cryptos or the link in my profile.
