I have read several posts on this forum where people have claimed to have invested all the money they have on Bitcoin, I also read a post where a guy claimed to have used all the $20,000 his uncle gave him to also invest in Bitcoin, some even sold their landed property. The reason for these risks and others is the firm believe that Bitcoin would be $50,000 - $100,000 by the year 2019 or thereabout.
First, I must say that I admire the courage and high risk appetite of such persons. But, I must also warn.
Yes, It is good for everyone to have high hopes for Bitcoin, and also hope it gets to 100k USD in future, but you should also consider a safety factor in anything you do including investing.
Mathematically,
DO NOT Assume,
P(Success of future term) = 1 ; and
P(Failure of future term) = 0
This implies that, you must always leave a little fraction for probability of failure which in this case is the safety factor, no matter how little the fraction may be. Simply put, you don't have absolute control of what happens to Bitcoin and Cryptocurrencies in the future.
Invest wisely, only invest what you can afford to loose
Just a piece of advice.
What are your own suggestions?
Yes, I agree with you that we should not invest all our money in bitcoin and cryptocurrency. because this investment has a big risk. ryptocurrency can provide big profits with fast time but can also make bankrupt in an instant. we should invest as much as we can to lose it. and if you have a lot of money you should divide it into sections. so we don't only invest in cryptocurrency but also in real estate or property. Investing in property is also beneficial because the value of buildings and land is always rising every year.
