Yes my friend also said like you, he said if gold is an old investment. It is true, in the modern era, bitcoin is a new and best investment. For long-term or short-term bitcoin investments it is an ideal choice because of the fluctuating bitcoin prices and rising prices will be able to make a profit. But there are still many people asking whether bitcoin is worth investing for more than 5 years because it is so volatile that fear of sudden prices could fall, but I believe bitcoin will continue to grow and fluctuations tend to rise. This is proven when the price drops not long the price recovers and rises again
I'm not sure if Bitcoin is the best investment out there presently
Especially for long term investments since these investments don't need the exponential growth which is not based on real progress or adoption but purely on relentless hype and runaway speculation. Such growth is likely to end up with an implosive collapse one day, which renders the whole idea of long term investments futile and fruitless. On the flip side, though, I agree in general that for short term speculations (let's call a spade a spade here), Bitcoin is one of the top-notch ("state of the art", as it were) tools freely available to everyone with a fiver in his pocket
