Even if your trend judgment is correct, do not heavily invest in altcoins. The only thing you can heavily invest in is Bitcoin. You should know that retail investors are completely transparent to the big players. The big players know your opening price and your liquidation price. Once the big players find that their manipulation will end up benefiting you, they will deliberately crash the market. If you are bullish, it will stubbornly not rise; if you are bearish, it will slowly fluctuate downwards. In any case, they will torment you until you exit before the market starts moving.
