I think you have lost your asset which is now worth .I also did a mistake .I had some btc but i sold it very low price when it was too low in price .I even see many ups and down on the market even we get btc on very low price ion 3000$ on the recent past .I think we made huge amount loss as we didn't buy a few .He who invested their capital into btc they have already been rich .I think its is very risky to enter now at the market because the price is going to the up and over .I still want to buy few btc if a get the price on low ever but i will not get such a chance ever .
