The value of your coin can increase when you buy at a low prize and keep it for a particular period of time to sell at a higher prize. Please be patient with the process and have a firm believe. It is called Holding.
In my opinion, what you mean by coach or mentor is a leader who can educate the public about investment in Bitcoin. If I have not misunderstood, I agree with your words. Because investing in Bitcoin without knowledge is similar to driving a blind person. Investing in Bitcoin requires proper knowledge that teaches you to enter or exist at a perfect time from a long-term perspective. And at the same time, if you are familiar with technical and fundamental analysis, then you can go for a Bitcoin investment, which can be helpful in making a profit.
Cryptocurrency investment is risky, so you may need a coach or mentor and if you cannot afford, always read the valuable content posted on BTC and Cryptocurrency in this community as there are many topics that can be useful to your growth and development.
If we look at Bitcoin, it meets the criteria for a holder. Meaning, for long-term holding, you should hold the coins that are not pieces of shit and do not have pump-dump qualities, meaning that the price rises in the long term at a consistent level. And everyone knows that it is Bitcoin that is going to rise in the long term.
So that means choosing only Bitcoin for your holding strategy. Pick up altcoins for short-term profit because there are many altcoins that were at their peak in the 2017 bull run, but when the bear cycle started, they grew at a very low price. People have high expectations, but they will reach their peak in the same way. But when the bull run of 2021 came, the name of these coins was not among the top coins. Therefore, only Bitcoin is reliable for holding beside Altcoin for a short time to gain profit.
