As you rightly stated regarding altcoins, there has been a healthy market where innovations include staking and contracts make it an option for those deciding to avoid investing in Bitcoin. As long as there is diversity as options, investors should be happy but they should do their research before going proceeding.
I believe this is why we have bitcoin, which is the main and original cryptocurrency, and we have altcoin, for those who are looking for an alternative to bitcoin in cryptocurrency investments and trading.
And when we come down to worldwide investment assets in general, we have company shares and bonds, we have the real estate, we have land and properties, we have precious metals, we have cryptocurrencies which happens to be the latest innovation, and so on.
And coming to shares, tesla fall under it, and coming to cryptocurrencies, bitcoin fall under it, all this are investment opportunities created for man, Anyone anybody is comfortable with, he or she will go ahead and invest in that area, this is the beauty of choices, alternatives, and diversity.
