When the price of Bitcoin reached $38K I thought I would sell my investment but I didn't sell my investment yet hoping for something better. Thinking whether to sell the investment or not I thought I should share the matter in the forum and I will get the best solution from the forum that's why I am sharing the matter in the forum whether I should hold on to my investment or sell it now.
I don't need the money anyway, if I sell my investment now I have to deposit this money in the bank again.
Regardless of the fact that this is a Bitcoin forum, I will say that maybe you should sell because you obviously do not feel comfortable investing your savings in Bitcoin, regardless of the fact that you claim to have known about Bitcoin for a long time.
I can conclude that ignorance, doubt and greed are a very bad combination in any investment, and in that case I suggest to everyone that they prefer to keep their money in the bank, or to buy government bonds or something similar - the profit there is not great, but you still sleep much more peaceful.
That really be the best decision he could do since if he keep holding it for sure he gain a lot of pressure due to price changes happen. So he should experience to sell it first then try to monitor on how the market move after that so he can get an idea and learn from the action he made.
The three attitudes you mention is really a bad combination since it can make people not to think more clearer regarding on what price they want to take their profit since what came up on their mind is how they can earn more in ongoing good tracks of the market that's why they will hold more and stressed their selves on things they don't understand. Maybe best for them to keep their money in the bank for safety if they are not prepared, but its also good if they try the risk so that they can able to experience the worst and bad situations on the market.
