The best lying in ambush currency (c r v) (l o o k s) (c 98) The secret of my profitable long-term contract for more than 4 years is not to play $B T C$ or $E T H$, never short contract currencies, not to chase the market, and only arrest oversold currencies in each round of decline. Chasing the market will regret for a lifetime, while buying low will make you rich for three generations.
