GFT has just broken through an important resistance level, experiencing a long-term decline and accumulating a large number of short positions. If it explodes, it will take out a lot of short sellers, leading to a breakout and an inertia surge. If there is additional funding later to ignite it, there is a chance to reach an unexpectedly high level. It may be worth taking a small position for a gamble. There are not many opportunities with Bitcoin and Ethereum; only ultra-short traders can capitalize on arbitrage, which requires high technical skills and has limited operability. Therefore, one can look for suitable altcoins to catch the breakout point. Fuhaitang has mentioned that futures are all about breakout; one successful breakout is enough for a good meal. Stop-loss can be appropriately enlarged, and it is advisable to use funds that won't cause pain when aiming for a breakout.
