What caused it?
You seem to be confident that there is a buying time now but what makes you so sure? After all btc could drop to 5k and then you would lose 20% if you go in now.
I agree, my opinion is to wait, BTC'll go lower for sure, under 6000 $, waiting strategy is now the key.
If everyone just stays on the sidelines then nothing is going to change either. Look at the low volume that tells everything. If the majority of people just sits this out we never get somewhere. I think the big shift need to happen from speculation to actually using all these currencies in daily life. I try to buy with Bitcoin whenever it is possible but just very few sites accepts them as payment
