100 push ups a day until Bitcoin gets to £100k that's a nice one and I think I'm caught up in this owing to the fact achieving this has to come through a process for someone like me who hasn't been too frequent with fitness I will have to draft out a daily plan .
In my plan I'll keep observing the rise in Bitcoin and I must ensure that I bit the 100 push up before Bitcoin gets to £100k . 
My daily plan
Day one .  25 push ups
Day two.   35 push ups
Day three. 45 push ups   and it runs simultaneously till it's achievable but this is totally going to be dependent on the percentage increase in Bitcoin over this period.
