I think the title says it all.
After a long time of thinking, reading and also investing a bit into Bitcoin I have to say that it looks for me that the main use is actually just pure Investment. It always looks like that everyone just talks about how great the Technology is although they secretly want to get super rich with a always raising price. Of course it's used with several shopping or daily things, but that's just such a small part of it.
During that, people who don't want to take the risk to invest call it a "Bubble" and people who don't want to lose their money just make kind of stupid speculations without any arguments.
In the end (just my opinion) the price of Bitcoin is controlled by all the media (that's hyping bitcoin and talking about it everywhere) and all the really big bitcoin whales with e.g. like 10000+ coins can actually effect the market the most. Imagine what a few people with a huge amount of bitcoins could work out together to control the market and making money.
It's just weird, because it turns this, what everyone calls it, great technology in the end just to a fully commercial object to earn money. Which would be probably also the reason why it stays and raises all the time, because it's normal that everyone wants to make a big amount of money with this little effort.
Let me know what you guys think and please don't give me this non argumented one liner like in all the other threads
