I'm curious, how it's been working out for you, OP? I'm thinking about selling all my remaining coins and turn them into BTC.
I just stumbled across this thread after un-ignoring Bitcoin Discussion, and I'm curious as well--though if what OP said is true, he's been accumulating bitcoin since 2013 and probably hasn't sold any of his stash. Presumably with the price increase we've seen in the past day or two, he's still doing just fine.
I don't know about keeping all of your investment money in bitcoin for the long term, however. OP will likely still be in the black even if bitcoin were to lose half its value (if he's holding onto 2013 coins), but if I were him I'd probably diversify just a little. Normally I'd suggest the stock market, but after well over a decade of bull market craziness I'm not sure now is the best time to buy stocks.
OP, you still around? Maybe you can chime in and give us an update on any changes to your portfolio, etc.
Still all in BTC, doing fine, no headaches watching the shitty coins. Not planning to sell even if BTC price is going up right now. Might sell a small amount once in the xxx,xxx range and then hopefully will buy it back, I'm sure we will see a new ATH this year.
