So at what point are you happy with the recovery / profit? You bought in the low 200 range, it was a good time to pick up quite a lot of coin for me as well. Is this price enough for you or do you feel greedy and want to go for the top?
I believe Bitcoin has the best potential to equal or even surpass the level of the USD/Euro/JPY/GBP/Yuan/etc. (if the transaction throughput problem is solved, paving the way for use as a global currency), gold/silver/diamonds (if it instead remains primarily an inflation-proof store of value), or both. If that happens, we are talking $100,000/
BTC minimum.
I also believe Bitcoin has the potential to be surpassed by another crypto (more-likely) or fade away like tulip-mania (less-likely). Thus, I have invested an amount I am comfortable never seeing again and have resolved myself to seeing the result of this binary proposition through to the end.
So to answer your question I am definitely happy with the growth thus far, but I'm in it for the long haul. The interesting thing about that is that by the time I would ready to take profits, the logical choice would be to take the profits in Bitcoin.
