And once upon a time, Tulips were the new medium of exchange in Europe. Many invested in the new medium, there was a weird tulip inflation and then, poof. Crash of the Tulips. Many bankruptcies of people and firms that should have known better.
I believe that is what the pitiful investment comment meant. Buying up a new and rather strange medium of exchange was a tulip fad bound to fail.
What are some of the concerns you have over Bitcoin besides the fact that it is "new" and "strange"?
I remember when people thought debit cards were "new" and "weird". Do you realize that most of the "dollars" you think you own are no more than 1's and 0's in a database? Your ledger balance with your financial institution is your store of capital. Your debit card or any Federal Reserve Notes you withdrawal is your transaction currency.
When you think you are taking your "dollars" and giving them to McDonalds by swiping your debit card, you are actually authorizing your financial institution to decrease some 1's and 0's in your ledger and increase some 1's and 0's in McDonald's while transacting through a mutually trusted network owned by VISA who charges a fee. If you think that system of exchange is efficient and beneficial to you then you can keep using it. If someone else would rather retain control of the entire transaction between the two interested parties and pay a minimal amount in fees they can choose Bitcoin.
Again, I would restate that normal people don't "invest" in currency. The people who do so are speculators or commodity traders. There is some amount of risk inherent in any occupation and I won't criticize them for their chosen profession as long as they face the consequences.
Do you think the folks in Ukraine who's currency has cratered and who are subject to currency controls value some of the aspects of Bitcoin right now?
