Right now, I can use my bitcoin holdings to pay for purchases at Overstock (OSTBP), or book a hotel on Expedia (EXPE). But if I use bitcoin to buy $25 worth of socks on Overstock today, and the price of bitcoin quadruples next week, I'll feel like those socks actually cost me $100. Then again, if bitcoin crashes, at least I'll always have the socks.
Transactions made with funds in a bank account can take a while on Coinbase - generally about 4-5 days business days. And using an account allows users to buy and sell crypto, to deposit money in, and and withdraw money from their Coinbase account. Bank accounts are generally recommended if you are dealing with larger investments and purchases - at the time of writing, using a bank account allows for users to spend as much as $11,250/week.
This serves a dual purpose of both allowing extreme transparency when desired in making transactions, and also allowing a lot of anonymity when desired. If one wants to ensure that they have perfect undeniable proof of their transactions, all they have to do is prove they own certain bitcoins, and then any and all transactions conducted with those bitcoins are undeniably theirs and most certainly occurred.
This system holds a lot of advantages even over gold’s natural system of being mined out of the ground. Gold’s mining is effectively random and not dictated by any perfect computer algorithm, and is consequently much more unpredictable in its output at any given moment. If a huge supply of gold is serendipitously found somewhere, it could theoretically dramatically inflate the rate at which gold enters the existing supply, and consequently cause an unanticipated decrease in the unit price of gold.
Virtual currencies, including bitcoin, experience significant price volatility. Fluctuations in the underlying virtual currency's value between the time you place a trade for a virtual currency futures contract and the time you attempt to liquidate it will affect the value of your futures contract and the potential profit and losses related to it. Investors must be very cautious and monitor any investment that they make.
