Everyone has their own favorite coin and this is their rights. I could earn more if i would just hodl btc instead of trading but i dont regret anything

Damn what a story. I can not comprehend what was going on in his head. If he just sold BTC, but man....

This is one of the reasons why I never recommend any cryptocurrency to my friends. Back in 2013 and 2014, I tried to convince my friends to make investment in cryptocurrency, but all of them ignored my advice. And now the cryptocurrency rally is there and everyone want my advice on which coin to make the investment in. I have told them that I don't want to give any recommendation. Let them learn the lesson themselves. Everyone want to become billionaires overnight and that's the reason why they are going for shitcoins. 2x or 3x return in a year from Bitcoin doesn't appeal to them.

I can never understand why people want on the short side against an asset that has proven to go up at average of 300% per year for the past 12 years when flattened out the volatility. That's such a bad risk/reward.

Well, at least you have tried to stop him at all cost now it is his own fault to suffer the consequences of the things he have done in the past. It is such a great thing to have a friend like you that are willing to give advice for a friend specially with regards to crypto but it seems that your friend really lacks patience and just follow his guts. There is nothing wrong on selling but better think of it to just sell a percentage or a part and not to go all out. Also, instead of putting your Bitcoin in line of selling, better get rid of other cryptocurrencies that you think serves no purpose or will have no improvement and focus on dealing with Bitcoin and worthy altcoins in the market. Also, you must assess the scenario. Sometimes listening to an advice can really do help but still it is up to you to do your own decisions since you will be the one to prosper or suffer the results of it.

Good that my friends heard me before and on time only they invested in it and on the boom time some of them made money and existed some of their position by booking profits. But atleast they are now doing well and at times buy and sell accordingly which is good thing rather than just staying away from it.

That is the common problem or situation that we may encounter for the beginners of the crypto world, some beginners choose to invest in shitcoins because they have seen the faster movement of the value of it compared to bitcoin. That is also what just happened to me before when I invested in tokens in the yobit invest box. I regret my decision of doing it because that token became a dead coin.

Patience is also important when investing in bitcoin, if you can't wait and you always have a doubt about bitcoin then you won't be a good investor. Patience is always the key plus the knowledge you also have.

Indeed, Bitcoin in 2021 shows an excellent result, its price has already gone to the moon, but as you correctly noted, this is far from the limit. Analysts say that BTC has passed only one-fifth of its path in this growth cycle, which means that the price of BTC from the current values ​​may still grow by 4-5 times by the end of this year. I agree that it is very difficult to keep your BTC and not sell it, but if you believe in success, then you need to find the strength in yourself and go this way to the end. I keep a little bit of BTC myself and regret not having bought more before.

You did what you could so I hope you do not feel guilty about it because this is not your fault, at the end of the day people need to take their decisions on their own even if the decisions are mistaken, while I am really sorry about what happened to your friend stories like that are incredibly common, people somehow think that bitcoin can be easily replaced when this is not true, once a currency has a monopoly it is incredibly difficult to get it out of that position and when that form of money is still the best then that is basically impossible.
