While that kind of knowledge is useful you  must also realize that there are exceptions to those rules, while I will not advice anyone to put all his money in bitcoin at the same time I could not blame a person if it did exactly that since bitcoin has been one of the best investments in history.

yes it is tue to invest money in btc than real estate or gold it will be profitable than any investment nowadays.

for me investment is good because through this investment many people become billionaire and the trade of these crypto currencies will lead to high profits and many of us now if we invest in this the time is near when we will be rich and successful in the crypto world. For me it is better to invest in profitable business instead of keep it without doing anything with your bitcoin. 

Yes of course if you do not have any plan to let your money work for you then just let it in the bank.  Savings is good but I will only do that after I saved an amount for emergency.  After that I will start to invest because it generates more income/profit. 

I think it depends. If you are capable to take bigger risk then you can earn money by bets on sports, trading or even online poker. Then you can invest in more risky projects, ICOs etc. But if you not comfortable with it then its better to take less profit and less risks. Real estate or Top500 is better choice then.

Nowadays, we don't need to save money in bank to have a passive income and avoid the situation "die" money. We can use it to buy real estate for rent, this is the best way for people have a lot of money but don't know any way or time to use it for investment.

Well I am not agree because the bitcoin is now very expensive and the bitcoin price and the importance is getting high so it is good to buy the bitcoin and to hold for the long time. It is being happened that the banks are now being robe and the people are robbing it to get the money so for me it is better to invest your money in the bitcoin because it is the safe and the easy way to get in the bitcoin.

we can also invest on many different businesses, or franchise. We can also put our investment on other peoples business, sponsoring them, and wait for them to grow and produce a lot of money. We can also invest by giving money to a fast food franchise that are already famous and know. Sending and sponsoring college students is an investment. after they graduated you can take them and make them work for your company for a period of time.

Btc is good investment form so i think its not a bad idea to invest money in btc rather than investing everything in the bank because you wont get much profit from the bank like what you can get from the btc the only difference is that you will get a small percentage as your interest forbe the deposit but they wont be any kind of privacy in banking system and they will be asking you for the source of income on how and from where they got the money to invest where as in btc there won't  be anything personal and you wont have to wait for longer time to get profit .whereas in the case of real estate it also a good option but in the current scenario it is running low where as btc is the best option to take profit in no time .gold is also a good form of investment which is being followed from ages.
