For me, bitcoin is the best investment in the modern world. Its price is skyrocketing, no matter what, and in the future creates the prospect of financial security.
Even if the price is pretty much stable it is still a good investment because it was shown to us many times that a year or two later the price will be higher thatn it is now. The only thing you need when investing in bitcoin is patience. Don't sell when it is dropping, wait patiently and you'll see it will rise in the future.
Indeed, it will be difficult to find something with more upside potential. But I advise you do not try all your capital invested in such a volatile asset, or you can be emotionally destabilized if the price falls too much, which can lead to bad decisions.
Yeah, investing all capital into any single investment is very risky. Thats why it is advised to have versatile portfolio to be on the safe side in the trading world. I believe that it is good to invest good portion of your savings into bitcoins because I see them as the future currency of the world.
