I am really thinking about investing over $15000 of my savings into Bitcoin. Would this be wise? Is BTC safe and stable at this point and this time?
It is not safe if you invest your all money it would be too risky, because the price of bitcoin is volatile so we don't know if the high price rate for today will remain the same in the next day, but if you have a great urge and your ready for what would be the result in your invest money, well it's your choice. But for my opinion if you've have doubts in investing your money I suggest to invest a small amount of your bitcoin so that it wouldn't a big lose on your savings, because we aren't sure if your investment will return the 100% of your profit.
This is a very valid option and full of protection, but if we take into account that everything in this life is a risk, then why not take it? Maybe you risk $ 15k so that you get in a not too distant time about $ 50k- $ 60k.
The worst thing that can happen is that you do not get to make a profit and that you leave with $ 15k or maybe a little less, but if there is belief in this technology, and in the market, in the stages of the market that are being fulfilled, there should not be doubt in the investment.
