You are correct, most users probably see bitcoin as a form of investment and not as a real currency. You can't really blame them, and although bitcoin may have been created to act as a currency in the first place, it is now following a different path. It's becoming a commodity that acts as a store of value. It actually suits perfectly in that category, and that's one of the reasons why everyone is getting crazy about it in Wall Street. It's gold 2.0 as a lot of people call it, and I think they are right for now.

Bitcoin can still work as a currency in the future, because it has potencial for that, if the network problems are fixed.
For me the big question is: if the network problems are not solved, will bitcoin have real use value, if it works just as a store of value asset?

I think that right now people are buying bitcoin for two reasons.
One, they just think it's price will go up (and this is of course a bad option in my opinion, because if the price stops rising and there is no real use for it, then there is no reason to hold, so people will sell and the price will drop).
Two, they think bitcoin will get mass adoption eventually and will act as a currency as well, that is way better than fiat because it solves many of it's current issues right now (I think i fit in this category).

So for me, the explanation of the bitcoin price, is in it's potencial to act as a currency in the future. It will not replace cash, but it needs to be able to be traded by goods or fiat, so it can really work as a safe store of value. People that buy bitcoin just because they think the price will go up, are missing the point.

Its not a stick. though its like a stock but ofcourse its not a stock.

Yes I understand that, and I agree with you right now. The thing is, that with larger adoption, and with a bigger market cap, bitcoin would get more stable. This is actually one of the problems that will always exist with the other coins like dash, bcash, etc, that are trying to become currencies before they become a real store of value, with a huge marketcap. US dollar alone has a marketcap worth of 1.5T if I'm not mistaken, and bitcoin is only at 130B. It's not even close to dollar, so of course BTC can't act as a currency with such a low adoption and marketcap right now.

The thing is, that even with slow transactions speeds, and moderate fees, there are people already using it to buy stuff. At least expensive stuff like houses for example. So it's already working as something that has value and is traded by goods. I don't need to use BTC to buy a tooth brush. Like I said it wont replace cash, and it doesn't have to.

If I can hod BTC as a safe haven, because it's decentralized and immune to inflation, and in the future I can buy expensive goods with it (not everyday grocery, because I can just use cash for that), then BTC will continue to have a future, and more people will adopt it. And yes, I used the word "adopt", and not "buy", because I think they express different concepts and points of view here.

Bitcoin price analysis theory is unpredictable  because  the market value price is volatile,but for now the value  in market cap of 1btc is mostly approximately $ 8000 to 8500 and maybe tomorrow or next week it will go down.the important is as long we gain profit in our investment everytime we trade or we hold our bitcoins if the  price is dump.so we invest wisely to prevent failure even our analysis is sometimes is not exactly.
