$BTC Losing 50% of 1 million leaves you with 500,000, and to break even on 500,000, you need to earn 100%—going to zero is a 30-second free fall, and getting back up requires bearing a 100% gravitational acceleration. Capital is your lifeline: a 100-fold return is a casino slogan; going to zero once clears the field. Remember: whoever touches your capital deserves to lose their hand, including yourself.
