i have no strategy,for bitcoin trading i dont use strategy,just like ordinary traders,buy when the price low,and sell when the price high,simple. but i dont think its can applicable to altcoin trading.
How do you know when the price is low? Is it low when it drops by $10 or maybe $50? If you buy at -50 what if it goes to -70? Do you buy more or wait? It's not that simple.
