if you sold at very high level, it's a good time to buy again and take an huge profit, you can probably do x4 if you sold in the good old day of the 800-1200 range
I doubt he has sold at this range. Actually, he hasn't even sold his coins, he had just spent them. If he has sold exactly about 2 years ago, then he came back to pretty much the same level or the Bitcoin is even a bit higher in the price then exactly 2 years ago.
Welcome back OP anyways, I am sure if you decide to leave for another 2 years, we would still be here, don't know with which price though!
