Is it true that its wrong to hold coins for many years and never look back? Someone said coins can die in just two years, they can also lose demand and hype under a year, so how do one hold with zero worries?.
If you are planning on HODLing, at least invest in a coin that is stable enough for its price to hold in the market (e.g. BTC, ethereum, XRP, etc.). In addition, to the people who say that they invest without looking back, that is definitely some bad advice there. Regardless if you are HODLing for short or long-term, you must create a plan on when you should cashout. This should always depend on the % of profit you are comfortably selling.
Let us say that you purchased BTC at this current price (e.g. $30,000), then you could sell those coins once its price doubled on the market. It does not necessarily have to be a solid two (2) years, but it must be align with your goals on why you invested in the first place.
