blockchain. Bitcoin started in 2009 and blockchain started in early 2014

bitcoin is an application. In order to achieve some of the purposes of bitcoin, some technologies are used, because bitcoin is more and more valued by the market (that is, the price is getting higher and higher). These underlying technologies are later refined and called blockchain separately
then, their relationship is similar to that between internal combustion engine and automobile
in order to run, cars use internal combustion engine technology
the internal combustion engine technology is also widely used in trains, small power stations, agricultural machinery, engineering machinery, merchant ships, conventional submarines and small airplanes because of the wide application of automobiles. The number of internal combustion engines in the world ranks first among the power machinery of human beings
if you understand the relationship between blockchain and bitcoin in this way, is blockchain technology important
it's important, but more important is the structure of all kinds of human data and the decentralized future realized by this technology.

mining, I don't think I can make much money, because. Now there are not many people who rely on their skills. Most of them should rely on mobile phones or software apps to make money.

computing power, on the other hand, it is because of the decline of bitcoin price. Now people's mining is just a kind of psychological expectation compared with the price of bitcoin. But mining can not be completely unprofitable, if conditions permit, there is still a certain profit margin. For example, the TV you use for mining is free. Or use the latest Avalon three generation miner for mining and so on.
