Bursting bubbles usually brings price below the values when pump started.
$700Million Tether were "printed" between January and November 2017
$700Million fake Tether coins pumped only in December 2017 pushing price from 8000 to 20000.
Next $700Million were in January 2018 trying to hold the bubble at least above 10000
If 7500 Buttom holds we will reach 15000 till August
In case $6500 bottom would be the minimum, then 10000 would be available in August
But I am pessimistic that the worst case would be with $4000 as minimum, which is corresponding the real price of bitcoin without tether pumps
This is then a normal linear grow and no more parabolic but still 10% per Month, which is huge in compare to any stock in usual markets and forex.
