The only way to profit from a bear market is to buy at a lower price and sell once it appreciated. Assuming you are already holding a position you can only profit in a bear market by introducing anew fund and that will be only possible if you have the money. You do not get tired of holding when the market is against you because if you sell off it means loss.
Im not sure you have fully understood of a btc market with leverage products. You can go up to 100x margin, so lets say you use 1btc at 100x which would equal around 100btc worth of contracts for a short position indicatong you expect the market will decline in value. If your speculation is correct and moves just 1% in fhe correct direaction of your speculation then you have just made urself 1btc or 100% profit.. hence why im mainly offering this service as most dont even realize that opportunities like this exist within the crypto world.
