When he bought his bitcoins, it have a very high risk that time. Bitcoin price was not that high, and very much volatile. I admire his discipline in holding all those time up to the time he sold it. There are a lot of up and down during that two years but he still hold on his bitcoins. 300% profit is not bad. He should be satisfied with it. He can do it again in the future.
The higher the price is, the lower the eventual rewards will be. I doubt he will be able to keep holding from current levels till he's up 300% again, as the price would need to reach around $2200 at some point in the future. Other than that, ups and downs don't bother long term holders as their target is to sell when they reach a minimum of 100-200% in profits. If I look at myself, then I still have some coins that I bought in 2013 for around $25 untouched in my wallets. I have gone through a roller coaster where we went from an ATH, to far below $200, till where we are now. I still have them. Was I tempted to sell them at +$1000 prices? For sure, but I kept holding them.
