A lot of you are addressing issues that are confined to Bitcoin itself, but there are several others that have already addressed some of the disadvantages some have mentioned here.
The ethereum blockchain for instance allows for smart contracts -- this enables recurring billing based on a smart contract / decentralized app (dapps)
The IOTA Tangle (IOT, currently #8 at coinmarketcap.com) is not based on the blockchain at all. Instead, it uses its own distributed ledger via a DAG (Tangle), Direct Acyclic Graph, which allows for:
- Feeless transactions
- No mining (Each transaction verifies 2 other transactions, the peers do the PoW)
- Quantum proof
- Scalability. It gets faster as the network grows
As someone who's about to be employed in this space, I guaran-fucking-tee you that:
- Cryptocurrencies are only going to grow in popularity
- They're going to improve
- The blockchain and other ledgers (like the Tangle) are going to transform just about every industry
What I'm wondering is when someone will build the first decentralized TGP
