For me I think it could still be profitable to invest to Bitcoin but the risk is high at the moment. Well it still up to you if you could manage to take profit that's good and if not well I hope it's a lesson that you should only invest when the price is low.
Investing in any coin when the market is moving higher is always a risky proposition, i was waiting for the market to have a correction on reaching the $10k valuation but the market took off and i really missed the opportunity to invest further but i am waiting for another correction so that i will be able to invest and ride the rally.
