We had Segwit deposit addresses, Segwit hot wallet refill and segwit cold wallets on the day of activation on btcpop.co
Just to realize that the change goes straight to a p2pkh address when processing withdrawals.
Its easy to blame services but maybe blame Core for still not having a fully supporting wallet?
Most services use the json rpc of bitcoind, to support segwit now we would need to move to raw transactions and change all transactional code.
Where is the point in making so much propaganda for segwit and that most are ready for it but then not even supporting it in the core wallet?
Its now nearly 4 months since activation of segwit.

For sure i'm not going to invest money to create own work arounds or own patches to core code.
We're investing to offer all features in other currencies soon so users can use the features with low fees.
Even the segwit fees are now in avg higher than the non segwit before activation.
There is really no point to invest much time and money to support something what doesn't solve anything at all.
