The sustainability of the Bitcoin rebound has exceeded expectations, with the current price already 5% off the cost line for building positions. Fast profits can easily be exciting, but I remain conservative in my approach: I do not take a rise as inevitable, let alone confirm that breaking away from the cost line of building a warehouse ≠ a solid bottom. Judgments like '100000 is the bottom' and 'Immediately reaching a new high' are too early and naive. My current approach is simple: take profits to ease the pressure of holding positions, and let the market go its own way.
