In January, I only leveraged long on ETH, not on other coins. Trading altcoins easily leads to frequent stop-losses, and they can fall into a bottomless pit without controllability. Even if I go long on ETH at 3330, with a stop-loss at 3300, I'm only risking one point, which is manageable. My reasoning is: when altcoins rise, ETH must rise; when ETH rises, the altcoins you hold may not necessarily rise. Most altcoins tend to rally for a few days towards the end of the market cycle before retreating. I will invest in leading altcoins in batches with 2x leverage at the end of January.
