I only love single bets, but bookmakers love everyone who bets multiple bets.
Of course, bookmakers love everyone who that makes multi bets - after all, it is the combination with the greatest risk. Multi bets are often as risky as a lottery. The probability of surprise then is several times higher. Basically as many times as many matches we combine

However, once we manage to hit, the rewards are also much better

Anyway, now I don't have to bet, I have to stay still, because I'm losing a boat of money, I bet on the rise of the BTC by June of this year, but today I'm at a 35% loss.
Today BTC price is crashing! I predict drops until the end of March. The price increases in the second half of the year. At the end of the year, maybe even a new ATH.
It can still happen a lot, but in my opinion you will lose this bet. If the situation with coronavirus will not be controlled fast, it is unfortunately possible, that it will be even longer bear market.
