Hmm, that's good advice regarding the Bitcoin investment from your friend. But I think you should not have involved yourself. Meaning, you should just tell him that Bitcoin is one of the best investment assets that can give you a big return. And at the same time, be alert that it is a volital thing that is dynamic with profit and big loss. 
 
I really appreciate your work. OP, you gave good advice about investing in Bitcoin, but one should not advise anyone with the same style because it leads to financial abuse. Your thinking was right, but the style was wrong. Because if your friend loses, he will blame it all on you. Obviously, you had advised him to invest in Bitcoin. 
So let him know more that if he is really interested in investment, tell him to divide his funds among the whole fund of the company. One part is main capital, the other is emergency funds, and after that, whatever is extra, he should invest in Bitcion and invest in Bitcoin also under the DCA strategy and hodle for the long term, then he will surely organize big margins of profit.

DYOR !

This days, with how fiat currencies are losing value rapidly due to high inflation, I will not say that this is a bad advice, atleast, if at all I was in your shoes, or find myself in this same shoe anytime in the future, this is exactly what I will also advice.
Bitcoin over the years have proven to be a trusted store or value that won't fail, as long as the investor is only investing money that he or she plans to hold for a very long time, and he or she is also patient, such investment will always pay off, we have alot of persons and companies to reference in this context, and aside Microstrategy, we have the president of El salvador as another notable person who have succeeded in placing El Salvador in the world map by not just his strategic investment in bitcoin, but also the way he strategically adopted bitcoin and made it a legal tender in his country, today, we celebrate El Salvador for their enormous various achievements all by the help of them having a visionary president who saw the future before everyone else in the country and decided to give his people a better life by investing their country's treasure in bitcoin.

So, in essence, investing in bitcoin is one investment plan that possibly will never go wrong or soar, if (like I said before) the investor is patient, and it's better to hold bitcoin than hold fiat, since fiat are designed to lose value and purchasing power overtime, while bitcoin; due to its fixed supply, is designed to increase in value, gaining purchasing power over time.

I will not say your advice is wrong but I will say that some words should have been added here. And they are thinking that bitcoin investment will always bring profit to all companies but it is not correct because bitcoin investment has high volatility and that can push up a company just like it can also worsen their economic condition. Now I think if a company wants to make bitcoin investment then they should first know how much their own affordability is, they should understand if they can survive the bear season by making bitcoin investment.
And I think they can invest that much on bitcoin as the afford. So that later in the bear season they can run properly in their company. The company called micro strategy has made a huge amount of bitcoins and we have to remember that micro strategy has made such a big investment because it affords that amount of funds. So because Microstrategy has made such a big investment, there is no point in saying that we all have to do it, we must understand our afford and then make the investment.

Kind of, I mean, you should have let him figure it out what he wants to do. while I get what you are trying to do, I still think what you did inappropriate. People need to figure out what they want to do with their money. It can become a disaster if your friend took you up on your advice without properly preparing for what he is about to do.

You aren't his legal financial advisor. So you shouldn't give advice this way. But you may explain to him about Bitcoin and how it works. He has to know what Bitcoin actually is and how it could be beneficial for him. So once he understands everything, he might make the decision himself. You can't compare other companies with MicroStrategy. They have a different strategy to accumulate bitcoin. They have a legal team to take decisions, and they are investing a part of the profits. So even during the dump, they don't need to be afraid or panic. So I will advise him to learn about crypto and make his own decisions. 

Yes, it can be certainly good but a risky one. There are still no guarantees that if you invest in bitcoin, you will end up with significant profits, that only happens for those who have been hodling their bitcoins for too long, probably 5-10 years without having an attempt to sell them earlier. Now, I don’t think that long term hodling will be applicable to the company funds because I believe, those funds will serve as a back up for the company in case some budget shortage will occur, and if you invest it into bitcoin, you are already defeating the purpose of that money stored in a bank.

He can actually invest using his own funds, at least if he lose partial of his funds, that won’t be an issue since it won’t compromise the company funds.

Suggestion to investment in Bitcoin will be always good but the basic things should be followed and the things are afford zone of the investor. Your friend has the company and the company was his father first of all he should be taking care of his company rather than going to any other investment. And after that if he have enough money for investing then he should know the analysis the basic of Bitcoin then he can invest. I would like to say to you that say your friend first of all figure out the Bitcoin investment then invest.

Did your friend even knows about bitcoin? If he doesn’t know about bitcoin, you shouldn’t just ask him to invest in bitcoin without having proper knowledge about bitcoin,  don’t you think he might end up losing the bitcoin and they business is going to crash, and you are going to be blamed for that because you encouraged him to invest in bitcoin. You shouldn’t use Microsoft as example, you just said it’s a small business which am sure will be handled by just few people, if anything happens to the money in the bank, they might not be able to run the business again, but if Microsoft lose their bitcoin, their business will keep on running.

Since they are just handling over the business to your friend, then the should just leave the money in the bank first, to understand how things works, maybe when your friend has settled down, then he can start investing some of his profits in bitcoin, but don’t invest all companies money in bitcoin.

Advising to invest in bitcoin is the right decision but your friend needs to know more about bitcoin before investing based on your words. Because the future of his company is involved with bitcoin investment, he must know the basic things of bitcoin by doing market research. Bitcoins are not static so if you see the price drop after investing you may be blamed. That's why your friend should know all the information about bitcoin market and then invest.

Your advice is good, but he needs to know whether the money will be used to develop his company or free money that can be used to invest in Bitcoin. If the money is for the development of his company, he should not use it to invest in Bitcoin, as that could disrupt the company's finances.

If his company made a profit in the previous year, he can use the profit to invest in Bitcoin. That will expand the number of assets, not just the company.

You can give advice like that, but it will all come back to him because he is now the owner of his company. You can teach him about Bitcoin first before suggesting he invest in It. He needs to know more about Bitcoin before deciding.
