The price of a bitcoin is influenced  by supply and demand. When demand for bitcoins increases, the price increases, and when demand falls, the price falls. There is only a limited number of bitcoins in circulation and new bitcoins are created at a predictable and decreasing rate, which means that demand must follow this level of inflation to keep the price stable. That’s to say Bitcoin is mostly influenced by the supply of Bitcoin and the market's demand for it. Also the cost of producing a bitcoin through the mining process. Because Bitcoin is still a relatively small market compared to what it could be, it doesn't take significant amounts of money to move the market price up or down, so the price of a bitcoin is still very volatile.

When a user loses his wallet details, I think it has the effect of removing money out of circulation. Hence lost bitcoins still remain in the block chain just like any other bitcoins. However, the lost bitcoins remain dormant forever because there is no way for anybody to find the private key(s) that would allow them to have access to the bitcoins and be spent again. I’m sure because of the law of supply and demand, when fewer bitcoins are available, the ones that are left will be in higher demand and increase in value to compensate. So I still wonder what then happens to those lost bitcoins, because I think since no one can have access to the private keys what about the developers of the blockchain app? Can the developers of block chain gain access to the lost coins and withdraw them from the lost account?

The links on the reply of my previous post has been so helpful to me, now I know more about Bitcoin, the rules guiding the forum and how it works. The only thing I knew about Bitcoin was how to purchase bitcoins at a Bitcoin exchange, sending and receiving of Bitcoins. But now I’ve read through all the links you shared and my knowledge has increased, I know one can also  Earn bitcoins through  mining. To my understanding, Bitcoin is still in the process of maturing and everyday we get to know more about how it works because nobody can really give an accurate analysis of what the outcome might be in the next minute or next day. There is no guarantee that Bitcoin will continue to grow or continue to dip even though it has developed at a very fast rate so far. There are various ways to make money with Bitcoin such as mining, speculation or running new businesses. All of these methods  involves risk taking so It is up to each individual to make a proper evaluation of the costs and the risks involved in any such project.

I joined this forum since September 15th but due to my health challenges I couldn’t be active to make posts daily. I feel better now and I have so many questions I want to ask to know how this whole thing works. Although I have Ethereum, a friend of mine adviced me to buy it a year ago and it is stored in my blockchain account, I see I have made profits and I’m not willing to sell it out for now so I understand the basics of how to send and receive Ethereum and Bitcoin through wallet address. But I was wondering, how do you actually get started with Bitcoin? I have read some articles about mining and the different things you can do to actually get some money in profit, but none of the articles actually go into depth with how to actually do all these things. I was wondering if anyone in the forum could help me and make any suggestions to me.

I have a good amount of ethereum but I’m also keeping it for future use. I really don’t want to trade it for now even  when I have financial challenges I still hold to it because I think it’s a good investment. I did not buy Bitcoin when it was cheap and affordable. Now it’s too expensive to buy. I am proud of my ethereum portfolio. It’s the only cryptocurrency I am holding. I can understand what libert19 is saying, I find it hard to sell my ethereum even when I am in profits.
