DeepVault is an information store that is held within the blockchain meaning that the data is immutable, forever! More specifically, DeepVault allows Onion members to store file validation credentials (hashes of files) within the blockchain. This has obvious benefits as it allows users to verify a file's integrity over time. Therefore, if the hash of the file changes, then the file has been altered or corrupted.
Not even close to be the number 2 BTC, it might be a strong coin at later time, but for now many members marked the project as scam.
The only technical aspect that can advance from Bitcoin is the transaction speed. I believe Altcoins transaction speed are ahead from Bitcoin's but in terms of value and price, nothing can predict what's the next Bitcoin because Bitcoin is already a decade old.
