So if I opened a ROTH now I would pay taxes on the amount of equity I put into the account this year. I can allow an investment (BLTA) at .0050$ time to grow and pay taxes on let's say $1000, so 3 years from now I decide to sell BLTA at .30$/share. The taxes on this equity were already paid for in full at the purchase time, prior to BLTA's appreciation and therefore I would not be paying any additional taxes on the appreciated amount ($30,000)...is this correct? I feel lime I am missing something..


Thank you,

And sorry for being off topic for the board
