Many people have already stated the reasons of increase in transaction volume and the real reason can be any of them. The bear market has already gone though.
The bottom was near $3400 after which the price had started to increase. We are just holding the price now to near $3900 since we have a strong resistance at $4000.
If we break this resistance then the price will further go up to next resistance level and who knows before breaking that one we might face a small correction too.
