Long-term holding of Bitcoin comes with additional risks, such as the potential for scams or hacking. These issues are common in the Bitcoin community, with instances of hacks worth millions of dollars often making headlines. These incidents can be caused by malicious websites or bugs circulating on the internet. To minimize the risk of losing your Bitcoin holdings, it's advisable to store them offline using hardware wallets or airgapped devices. While long-term holding is generally considered the best practice for Bitcoin investors, those looking for short-term profits may explore short-term trading. Keep in mind that engaging in trading requires bearing the associated risks, especially if you're not experienced in the field.
Hacking and scams are common in cryptocurrency, and the risks are high, but the biggest reason not to hold Bitcoin for long time is that we often miss out on the opportunity to make a nice profit in Bitcoin. The cryptocurrency market is volatile, so often times we make a good profit, but we also often end up at a loss trying to make more profit.
Therefore, instead of holding for a long time, one should sell when a good profit is made and wait for a lower price to buy again. If one has good capital, he can earn good returns even in short term investments. For short term you can trust any good exchange where you can keep your bitcoins for trade. Risks are everywhere whether it is cryptocurrency market, Bitcoin or any business. So we should invest or trade keeping all the risks in mind.
