me myself think this is the best time to sell your bitcoin. you might consider to invest in altcoin instead than bitcoin. cause bitcoin is not an company. what bitcoin do is for helping transaction and seems its fail cause bitcoin transaction fee is so high rather than other coins such as ripple and XLM. im afraid soon bitcoin bubble will pop. thats the reasons why you must sell it now. there is alot more reason to sell it and invest to altcoins. the decisions in yours hand and the risk is yours. its true there might be a chance for bitcoin to increasing but i dont want take such risk.
