Hey guys, thanks for all the input. I figure it might be useful if I add a bit more information as to what I plan to do when I decide to take profit.
Once BTC passes a certain price point I intend on DCAing out of my position, selling a small portion of my holdings every 1-2 weeks. I figure that this would help limit the risk of losing a lot all in one go if something goes wrong, but also I don't know how high the next ATH is likely to be, and I don't want to potentially miss out if I sell too much too soon.
My main concern is the bank deciding to hold or freeze my assets if they see what they consider suspicious activity on my account. If occurs to me that I could potentially give my bank a heads-up before I start making any deposits like this, and if that's a problem for them then I could open an account elsewhere.
