If you are a short term trader, you must place a long bet now because it's simply when BTC price bounces, it will go up to 3650 yuan easily.
In case BTC price goes down, you must set stop loss around 3490yuan.


so downside is you lose 50yuan,  upside is probably can go up 3650 easily so 90yuan.

almost 2 times more payout, yet up and down side is 50%

there is massive resistance on 3500. so it will not likely go below 3500yuan
