It is actually more profitable to hold bitcoin for a longer period of time than short term, some people can earn around 3% in daily day with short term trading, but long term trading or investors possibilities earn more than 150% profit earning from bitcoin.
Its depend how mindset and technical adopted by some trader when looking advantage or opportunities which one potential has large amount profitable with long term or short term investing in bitcoin.
I don't think all trader have diamond hand by holding bitcoin assets for longer time, they will prefer to earn much profitable than small amount profit with short term trading.
That is true that Bitcoin it more profitable to hold for long-term but long-term holding that there will be no risk of loss it is not true. Rather, if you do not take care in this case, a little careless can put a big investment at risk. Because there are many news articles where long-term holders have lost their entire funds due to their small quirks, even though there is more risk of being hacked than losing by trading. And in this case, you have to always keep yourself in check in the case of long term holding.
However, in comparison to Bitcoin or short-term trading, the risk of loss in long-term trading is less. But if you can't sell at the right time, many times emergency situations come and break the long-term strategy and face losses. So I think holding Bitcoin for long-term that doesn't mean that it's risk free.
