Hello again,
Yes, you have already requested this and I have implemented an on/off switch. It will be out today with the next release.
I highly doubt that this will improve your site’s performance.
If you have a large number of users, it is very likely that the delay is caused by the get_users_info JSON call. If you do not need to use the [wallets_move] shortcode, then simply disable the send_funds_to_user capability from your admin menu. This is needed only until I can improve the way [wallets_move] works.
Alternatively, it might be wise to reduce the number of coins that you have enabled in the CoinPayments adapter.
kind regards
