Not very educated in understanding what communism exactly stands for, are we?
That was hyperbole. Let's break this down.
Investment into BTC's unit price, means investment into new coin creation, which in turn means investment into mining.
There are half as many new bitcoins created per block every 4 years. That is to create artificial and predictable scarcity. Basically, everything is known in order to decide to mine bitcoins. Miners have to decide if it is a business they want to get into, not bitcoin buyers. Everything else right now is speculation until adoption increases.
To pay those who waste their money in building and buying the mining equipment, that doesn't improve anything in bitcoin's network or anywhere else. Investing into bitcoin means rewarding useless work. So, bitcoin can be taken as an investment, but it surely is a dumb investment.
What about non-mining Bitcoin based businesses? Are they dumb investments too? Who are you to define what work is useless or not?
It's smarter to look at BTC as an short term gamble, where you put some money in, outplay some other players and take more money out.
Life is a gamble, but you take educated risks. If you decide to take a chance on Bitcoin, remember that once you sell, you are out. When the next bubble comes, your orders may not be filled because the exchanges are unregulated.
