The Bitcoin network is currently experiencing a period of rapid growth. This is an exciting time to be in Bitcoin, and we're seeing all-time highs in bitcoin transactions processed through BitPay. However, we are also seeing rising miner fees for transactions across the bitcoin network. That's why (effective tomorrow) we're raising the BitPay minimum invoice amount from $0.04 to $1.00.
While transactions on the Bitcoin network are increasing, the current limit on transactions that can be processed in each block (group of transactions) on the network has remained the same. The network capacity will likely remain the same for the foreseeable future. Fees have increased to bid for the limited supply of space. Now that fees are reaching an average of $1 per transaction across the Bitcoin network, it's becoming uneconomical for users to make micropayments under $1.
It's also becoming increasingly expensive for BitPay to send these transactions to our exchange partners and merchants.
