This might be the reason why in the past 2 weeks there were 100 thousand unconfirmed transactions in the Blockchain. Most affected are those who are into investing, their withdrawals were put on hold. Well, as of now, it came back to normal. It regains its composure again.
No,it has nothing to do with unconfirmed transactions in the blockchain a few weeks ago,
Chinese banned their local exchanges to trade Bitcoin a month or two months ago,
and the real problem that caused a lot of unconfirmed transaction in the blockchain is the miner.
most of them moved their hardware/mining tool to mine Bitcoin Cash,that is why the confirmation take a long time to get confirmation.
the reason the moved it to BCH because they knew about the fact that it will get pumped so hard,
afterward they moved it back to Bitcoin until now.
