Definitely. The mempoor can definitely be flooded again like we had at the end of last year, but chances are it definitely will be less flooded due to the increase on SegWit adoption(unless we see a significantly bigger hype compared to last year's).
It really surprises me how many people and services are still not using Segwit though.
Even the Blockchain.info(now .com) still doesn't support segwit. Like what the hell?
It is strange that blockchain.com is still not support SegWit, they announced that it would be this year - but seems they are to busy with adding BCH and by changing the domain. Roger Ver was one of owners, maybe he have some influence even today - by what that service takes as its priorities, it is not hard to see what is going on there.
SegWit will be tested only when next big
BTC pump is start, but it is nice to see that almost 50% of all transaction is using SegWit. Since fees are too low most users do not see the difference and advantage of using SegWit, but when time comes they will switch to cheaper option.
