This is all gambles till we have real news. Don't blame yourself for not buying more or selling some of your position. Nobody knows what will happen with MCLN, this is a pinkie. It could have dropped to 0.0001 and at that point you would be happy for your sell. The people you see here are all traders, jump in for a quick run and then leave- good for them because so far it was an excellent trade. Most of us are here because we believed in the company and never thought we see 0.002.
Hang in there but don't put all of your eggs in one basket. If you are new, play in big board, it is much safer and the chance you lose all of your money is minimal. Play your beer money here...of course these are just my opinion.
Enjoying the ride like everybody else here-Good luck all
