but we have 30days, everything can happen so is safer to wait the last day and set a little higher "safe bet" on the best range, that range on the last day will have probably a range near 1.1
So base on what you said If I bet now 1 BTC on bitcoin with odds 3.71 as 1st picture and I will win my bet is not locked with that odds but if I will win I will get something around 1.2?
