In the world of the money market, prices can change at any time, geopolitical conditions now also affect market sentiment, even though the Bitcoin system is decentralized but the price is not decentralized, as much as possible you can see where the security is going because corrections can occur at any time.
The market can not be predicted. What do you mean by prices being decentralised? Am hearing such language for the first time.
A few years ago holding was very effective and promising, but nowadays it never guarantees that we will make big profits, this is because investors always sell when they get profit so the market is difficult to develop like a few years ago.
Holding is still very effective and so promising today like a few years ago for those who are patient. I do not bother myself that many investors are only out for the profit and they can sell fast. It is a choice and every investor should decide what they want, whether holding long term or not.
