Be more cautious about investing your 401k into Barry Silbert’s Bitcoin Investment Trust $GBTC. The (European) XBT Provider ETN is an open-ended fund which means it maintains a premium to the NAV close to 0% at all times. The Bitcoin Investment Trust is an inferior investment vehicle because it is a closed-end fund (it does not increase its holdings of the underlying asset when demand for the product increases) which means it is subject to wild swings in its premium, which has been as high as 150%. So you could make the mistake of buying when the premium is high and suffer swingeing losses even when the Bitcoin price is stable.
If you are going long, consider building an average position (for example via dollar cost averaging or value averaging). There is no better way to avoid making a poorly timed trade than buying incrementally instead of all at once and thereby buying an asset at its “average” price over time. If you don’t have a really solid grasp of technical indicators and the way the volatile crypto markets work, consider averaging out of positions as well. Averaging isn’t just financially conservative, it is important psychologically. Taking too big of a position at once can be emotionally difficult to deal with (and can thus lead to bad decision making) given the historic volatility of the cryptocurrency market.

All of those statements are false. I live in the US. I have the Binance app (there is a very simple tutorial on the couple of extra clicks required for ios, if you click on the link in the post above. And Tab Trader works just fine in the US as well if you set it up properly. There are tons of tutorials and videos that will walk you through it. If you aren’t willing to put in the time and effort to figure it out, that’s fine. But just because you can’t figure it out, doesn’t mean it doesn’t work just fine.
On the contrary, bitcoin has been widely used for international payments and is way more efficient compared to traditional cross-border remittance. According to Mr. Smith, “They use Western Union, traditional banks; It is slow and it is expensive. And there are people that can stop you from sending that money, whether that’s good or bad. With bitcoin, I can send money. It’s fast. It’s cheap. And frankly, no one can stop me.“
The next thing we’ll need to do is deposit fiat currency into our account. The easiest way to do this is by adding a bank account. Once you’ve initiated the deposit, it will take 4 business days to appear in your account. Kind of a bummer, I know; but the idea is to only need to do this once, as we’ll be growing this initial investment day by day with our trades.
Bitcoin has had phenomenal growth in its price and MCap since inception. If we exclude other cryptoassets, Bitcoin has been the best performing asset in the world every year since 2009 through to December 2017 with the exception of 2014. It has beaten all global currencies, equities, commodities, bonds, ETFs, real estate throughout that period. Bubbles are by definition short-lived, they do not keep bubbling for eight years.
Always pay attention to Bitcoin. Most altcoins (every cryptocurrency except Bitcoin) are pegged more closely to Bitcoin than Asian currencies were to the USD during the Asian Financial Crisis. If Bitcoin price pump drastically, altcoins price can go down as people try to exit altcoins to ride the BTC profits; inversely, if Bitcoin prices dump drastically, altcoin prices can go down, too, as people exit altcoins to exchange back into fiat. The best times for altcoin growth appear when Bitcoin shows organic growth or decline, or remains stagnant in price.
