The BTC.com wallet supports two types of cryptocurrencies: Bitcoin (BTC) and Bitcoin Cash (BCH).
Bitcoin was the first cryptocurrency and it’s one of the best known digital currencies in the world. Bitcoin has a block size limit of 1MB, meaning that one block can contain up to 1MB of transaction data. It means around 2500 transactions per every 10 minutes (4-7 transactions per second). Recently, due to the Segwit upgrade, the Bitcoin network can process more transactions.
Bitcoin Cash is a different currency. It was created as a fork of Bitcoin in August 2017, with the goal to solve the scaling issue that Bitcoin faces. Prior to August 2017, Bitcoin Cash and Bitcoin share the same transaction history.
Bitcoin Cash is similar to Bitcoin in most of its characteristics except its block size. Bitcoin Cash has a block size limit of 8MB, meaning that its network can process appr. 8 times more transactions per every 10 minutes. This allows for more people to make transactions at substantially lower prices, making Bitcoin Cash very suitable for smaller transactions as well.
