Update
Starting today, I've lifted the referral only requirement to open a Savings account.
The switch date is being moved to Aug 13th due to me being out of town and a delay in the rollout of the website update.
Any account that holds more than 5k BTC will automatically be upgraded to a Trust account on that day.
Accounts opened from today to the switch date will be paid the current rates until the switch happens.
Thanks,
