I agree never invest more then your willing to lose. But comparing bitcoin to yahoo is horrible really. Bitcoin is currency, you could make a argument its a industry but not a single buisness. And Yahoo had competition. Bitcoin does not really have competition as main crypto.
I disagree. Bitcoin is a currency that many, many people buy as an investment. All you have to do is read this site to find that out.
Whether an "investment" has competition does not mean much. An "investment" has to be shown as trust worthy and a future. It is too early to say that Bitcoin is either trust worthy or that it has a future. I'm not saying that it does not, but what I am saying is that Bitcoin will follow the principles of an investment for success or failure.
Yes, Bitcoin is more of an underlying technology, like the Internet - and not a specific company merely using it or operating in its realms - yet Bitcoin may very well still go wrong and also has competitors - other cryptocurrencies. Of all Bitcoin related currencies, companies, etc. investing straight into Bitcoin is still the safest thing, though. Calling that '
safe' weels weit, though...
