[On 29 June 2018, GDAX was replaced by Coinbase Pro. Somewhat different UI, but everything else unchanged.]

It's better to use Coinbase's sibling/partner GDAX (now Coinbase Pro) to do trading. Two main advantages of GDAX: lower fees, and ability to do stop and limit orders. Some disadvantages relative to Coinbase: fewer fiat/crypto/country combinations supported, have to have your fiat deposited in GDAX already before you can place an order to buy crypto, fewer features such as "vault".

Just create an account at Coinbase, get it all set up, log in, then go to GDAX and do a transfer of money from your Coinbase account to your GDAX trading account. Or you can just create an account directly with GDAX.

reddit's "/r/Coinbase"

If you create an order that goes into the "order book" (doesn't get executed instantly), you are a "maker" and pay no fee. So a "sell post-only" order to sell above the current price, or a "buy post-only" order to buy below the current price.

Cautions about stop orders, from people on reddit's "/r/Coinbase"":

Stop loss = market sell when stop price is reached.

Stop limit = set a limit; sell at limit price when stop price is reached.


You should be very careful when using stop orders. They are open to "slippage" and since the order book is effectively a queue of orders, your stop loss activates when a certain price point is crossed (when a match occurs between a buyer and seller, if I'm not mistaken) and your order goes in as a market order. This has higher associated costs/fees but also, if the price point was crossed as the result of a huge sell off, your (sell) order can execute at a much lower price point since you're effectively at the back of a long queue.

Another way to trade Bitcoin: use a normal brokerage account and trade "GBTC".

I think at some point the US govt will make a digital, crypto form of the US dollar, in addition to the current physical and electronic forms of it. Suppose the Fed issued, say, $100 billion of US dollar crypto-currency, in addition to the existing US dollar supply ? Best of all worlds: anonymous (maybe), digital, online, very low transaction cost, easily convertible, guaranteed 1-1 exchange rate with US dollar, backed by US govt.

Some basics:

A cryptocurrency may use several or all of these: For example, Bitcoin (BTC) uses blockchain, has mining and transfer fees, stores value.

Stellar uses blockchain, has transfer fees, stores any data ? Also Filecoin ?

User sends some coins of currency A to a blockchain for currency B:

I hear about this kind of error happening often, and apparently it's irreversible, the coins are lost.

But I don't understand: wouldn't this kind of error be EXTREMELY easy to prevent in software ? Software can simply check that types of currency match, before doing the transfer ? Maybe the addresses or transactions can have type of currency specified in them ? Or the exchange (which knows the originating currency type and destination blockchain type) does the comparison ? Is this not easy ? But maybe no exchange is involved, if doing a direct wallet-to-wallet transfer, or user-to-user transfer ? I don't know the right terms, I guess.

"In the past eight years, more than a third of all cryptocurrency exchanges have been hacked. The total losses exceed US$1 billion. Because cryptocurrencies are almost untraceable, the rate of recovery after a hack is very low."
