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?
Depends on what terms you want to risk you savings money, because if you want a short term only and you really want to earn money of you want to double your money in short term then maybe bitcoin is not good for you. But of you want to invest in long term and your are willing to wait when the time that bitcoin goes up and then you sell or convert your btc back to fiat then you can invest in bitcoin.
I am totally agreed with you, cause I know that Bitcoin is not a platform to double profit in a short time. even, if you invest money for a short time, then there is a huge risk to lose your seeds. Nowadays It is too difficult to predict when the market will go up or down. Those who are professional and know about the movement of the market very well, nowadays they are also failed to predict the market movement. I think investing in BTC should be done in the long term, then the chance of loss will be reduced and you will be able to make a good profit.
