Bitcoin is old, outdated slow and sluggish. Transaction fees, even when sending large amounts, constitute a significant part of the total amount, this solution will not work if bitcoin is to be available virtual money. That is why devlopers are working ond side chain solutuions like lightning network for fast, secure and almost feeless payments and RSK which is sidechain for runing smart contracts on the bitcoin blockchain.

Failure by design

First of all bitcoin has small blocks, and almost no exchange use segwit, that's why we are paying such fees. It does not have any scalling capabilities. Second of all developers of RSK and Lightning network think that they are able to solve thise issues with sidechain solutions and yes it will be somethng great at the current stage of the network while we have only 300000 transactions on bitcoin blockchain, but it will not be good solution after mass adoption.

RSK Scalling

Current RSK implementation can scale up to 400tx per second when node use SSD storage. Wow, it is a huge number when we compare it to the current ethereum capabilities also RSK smart contracts are written in the solidity so every ethereum developer can port his solutions with just few mous clicks. Also RSK promises that it will scale up to 2000tx per second, oh my god ethereum killer. That is not enough, not enough for real usage e.g visa handle 20000tx per second 10 times more thant RSK will be able to handle in the future.

Lightning Network Centralization

Payments in the Lightning network take place outside the main blockchain in the so-called sidechain. When you want to pay for a pizza you would have to open a channel in the lightning network, put some bitcoins in there and make the transaction the same would have to be done by any other person who wants to buy a pizza. This solution makes no sense because it means freezing a certain amount of bitcoins in the channels for each entity offering billing in bitcoins. Large hubs would have to be created that aggregate channels and redirect payments to relevant entities. However, this solution has two basic disadvantages that deny the bitcoin revolution. First, centralization and, secondly, very strong legal control as in existing banks

The future is somewhere else

Existing solution like Neo blockchain or upcoming like EOS system will change the world of blockchain platforms as well as the world of cryptocurrencies. More secure, scalable solutions must be created and implemented and that field of blockchain solution is something what will growth hughe in upcoming years.
