It fits me the big monthly increases. I usually take out profits every month so I can be more careful of budgeting my pocket and be tight with it.

Weekly basis won't work for me, I can spend the whole week profit within the day so small weekly increases doesn't fit me because I can also spend the capital that I used to start by a weekly trade.

Large spikes everyday is quite abnormal and large spike each year can be suitable also to us who have some other things to work outside crypto.
