Raw features from which the technical indicators are created

Features	Description	Features	Description
Transactions	The number of sent and received Bitcoin payments	Median transaction fee	The median of transaction fees in Bitcoin
Block size	Transactional information cryptographically linked in the blockchain. The maximum block size is currently set at 1 megabyte	Average transaction fee	Each transaction can have an associated transaction fee determined by the sender. The transaction fee is received by the miners who verify the transaction. Transactions with higher fees incentivize the Bitcoin miners to process them sooner than transactions with lower fees
Sent from addresses	These are distinct Bitcoin addresses from which payments are made everyday	Block time	The time required to mine one block. Usually, it is around 10 min but can fluctuate depending on the hashrate of the network
Difficulty	The daily average mining difficulty. The difficulty is computed by the network after a specified number of blocks have been created so that the time it requires to mine a block remains around 10 min	Hashrate	The daily total computational capacity of the Bitcoin network. Hashrate indicates the speed of a computer in completing an operation
Average transaction value	The average value of the transactions in Bitcoin	Median transaction value	The median value of the transactions in Bitcoin
Mining profitability	The profitabilityi in USD/day for 1 terahash per second (THash/s)	Active addresses	The number of unique addresses participating in a transaction by either sending or receiving Bitcoins
Sent BTC	The total Bitcoins sent daily	Top 100 to total	The ratio of Bitcoins stored in the top 100 accounts to all the other accounts of Bitcoin
Fee-to-reward ratio	The ratio of the fee sent in a transaction to the reward for verifying that transaction by the other users
