it's amazing how bitcoin has been uploaded lately:
0 $ -1000 $: 1789 days
1000 $ -2000 $: 1271 days
2000 $ -3000 $: 23 days
3000 $ -4000 $: 62 days
4000 $ -5000 $: 61 days
5000 $ -6000 $: 8 days
and still does not stop surprising us. It has been very marked the rise in the last month could be the result that it has become more popular and reliable for users. so it still has to climb
your times are a bit off the mark and also you should not use the price ranges like this. it is completely meaningless to do something like this. you should instead consider the rise size in percentages. for example from 1000 to 2000 is 100% rise but from 5000 to 6000 is a 20% rise.
in order to understand this better consider this comparison:
rise from $10 to $20
versus
rise from $5010 to $5020
you are right, I just wanted to make an estimate of the rise in days of course it have mistakes, I'm just a newbie who does not know some graphics!
