Taking deposits is a much better method for players than with what is currently being used by DirectBet. Bit365 was a book similar to DirectBet. Bit365 went under stealing player's funds. They were a non-deposit book.
The biggest downfall with using a non-deposit book is that you are at the mercy of transfer time between your wallet and DirectBet. Bets can be held for hours, using the worst case scenario, with a non-deposit book. During this time you do not know if you have a bet or not. If you use "firm odds", there is no way to cancel your wager. With deposit books, you get close immediate responses.
If you use the official Bitcoin client, your bet transfers will deliver within a second or two.
Unofficial wallets might sometimes have delays but this is something that they will solve over time and there is an alternative for the time being. Simply install Bitcoin Core and treat your wallet there as "Your Account" in books that are not taking deposits.
Note that the traditional deposit books force a delay anyhow when betting in-play, typically of 5-7 seconds, in order not to give an unfair advantage to those who are betting while physically presenting in the game.
This 5-7 seconds forced delay by traditional deposit books is equivalent to the time it may take for non deposit books to receive and process bet transfers and therefore there is no difference even with time sensitive bets.
In today's new virtual currency era, we believe that there is absolutely no need for a Sportsbook to take deposits and hold your coins while they are not being wagered.

When Bit365 went down the majority of the people who suffered losses were the investors, not the players, because they did not take deposits from players. The few users who got hit were those who kept on betting there while ignoring the slow pay warning signs. Later some kept on betting even when they did not get paid and as a result had accumulated multiple unpaid winning bets.
By the way, if you are curious why Bit365 went bankrupt, here is my educated guess :
They took around 500 BTC in investments and cashed some or all of it out while the Bitcoin value was around $100, then when the Bitcoin value went up to around $1000 many investors wanted to cash out but at that point Bit365 did not have sufficient cash to buy back the Bitcoins.
