Great exchange with passionate and helpful staff. HardBlock is especially great for regularly stacking sats and sending them back to your wallet. I compared CoinSpot Markets (low fee per transaction but high withdrawal fee), Bitaroo (great buy price and lowish withdrawal fee) and HardBlock (higher buy price but very cheap withdrawal fee). For the amounts I buy regularly, HardBlock works out cheapest after accounting for the withdrawal fee. Automated bitcoin withdrawals on the weekend once your balance reaches a you defined amount is especially cheap: only 99 sats! I contacted support with questions about Bitcoin privacy and was given expert advice. Justin went above and beyond to help me, levelling up my Bitcoin knowledge in multiple areas with clear explanations, links to articles and recommendations for how I can improve my privacy when using Bitcoin. HardBlock are clearly passionate about Bitcoin. They are involved and helpful in the community (/r/BitcoinAus). They are great educators through their podcast and newsletters. The HardBlock team are doing excellent work. I can't praise them enough. They also have the best name of any exchange!
