@oliverlai, The cost of transaction and the waiting times is ridiculous with BTC, and thats why it cant really be used for purchasing much things apart from things that price.

Currently Bitcoin is working pretty much like it did in earlier times - transactions are going through, there is no congestions, and one can get a transaction confirmed even with a minimal fee.

However, the main developers of Bitcoin thinks the congested situation is all OK. There is a hardcoded cap on the transactional throughput, meaning that Bitcoin currently can't be used as a a medium of exchange for the masses. Too many people trying to transact at the same time, and we get congestions. When there constantly are more people trying to create transactions than what the network can handle, we get longer periods where transactions are getting stuck despite quite hefty fees paid. And, surprisingly enough, quite big parts of the community seem to be comfortable with that, claiming that Bitcoin is meant to be a "store of value" and not a medium of exchange.

To be fair, they do have a road map involving second-layer-transactions, which may really rock (i.e. lightning network). However, the congestion problems and schism between "small-blockers" and "big-blockers" have been a big set-back for Bitcoin and crypto as such.
