But even with many success stories surrounding bitcoin investments, seasoned investors are voicing caution. Billionaire entrepreneur Mark Cuban and "Oracle of Omaha" Warren Buffett warn of bitcoin's volatility. Legendary investor and index fund mogul Jack Bogle, at a recent Council on Foreign Relations event, told the audience, "Avoid bitcoin like the plague."
For instance, if you wanted to send $100,000 of ethereum somewhere, you’d need to buy all that ethereum and withdraw over the course of 10 days (assuming you withdrew perfectly each day every 24 hours — realistically more like 11–14 days) back to Coinbase or your personal ethereum wallet before you could then send that ethereum on to somewhere else all at one time, like you would need to do in a token sale.
Bitcoin is a digital currency, also known as a cryptocurrency, and is created or mined when people solve complex math puzzles online. These bitcoins are then stored in a digital wallet that exists on the cloud or the user’s computer. Because bitcoins are not housed in bank accounts, brokerage, or futures accounts, they are not insured by the FDIC or SIPC.
