3) this might be a dumb question but is the price going to drop because not sure when i should buy btc i have about $1000 saved up and want to invest into it can someone tell me how it works lets say ex current price is 15k how much would i have made if i invested 1k with the current price thanks.
No one can really answer this with absolute certainty, but it has been speculated that the current bullish run is mostly caused by the upcoming Segwit2x fork. If past forks are any indication, the price will surge before the fork and slide after. Thus, if price is your only consideration, it's not entirely advisable to buy at the moment. It has to be noted that the fork is
said to be delayed or cancelled, but I can't vouch for the integrity of the news.
The current price is fluctuating around $7,500, so if you put in your $1,000, and its value goes to $15,000, then your investment will grow to $2000. If it grows to $10,000, then your investment will grow to around $1333. It's basic ratio.
