Bitcoin and blockchain are not the same. Both were somewhat hyped, but both deserve it imho.
Blockchain is a specific type of database. It has wonderful use cases, it is probably already in work for many businesses, but obviously not for all. However, since the governments started giving grants for blockchain businesses, some obviously tried to use blockchain even in directions where it's not the case, only to get hold of that money.
Bitcoin is a great tool for transferring value. It can be a great tool for store value (if it ever stabilizes). Of course, like everything that holds value, it's also used for speculation or as investment vehicle.
Right now Bitcoin price had a down turn. A bad one. Some investors/speculators have lost money. And?
Technologically Bitcoin is still great and developing.
Technologically Bitcoin is also great and developing.
Both have their use and development with or without looking every second to the price. And, just for the record, $20 and $1000000 both have the same chance to occur.
