Primedice without factoring in the hacks. Betcoin.ag does seem to have quite some bankroll but Primedice have suffered numerous hacks which took quite some hit to the bankroll. In terms of money making, Primedice does it the best.

With the house edge, you are expected to lose House edge% in the long run. Anything less or more than that is varience and will get even out in the long run. That is due to the chances being lower, in 2X with 1% house edge, you need to get below 49.50 or 50.50 assuming lowest possible and highest possible is 0 and 100 respectively.

The game that is demostrated can be botted since it is a client side game. The script basically automates the actions and thus cheats the game. For Bitcoin gambling, requests are sent to the server and process there. It is impossible for anyone to cheat the casino.

It depends. Most of the times, request are sent from your browser to the server, same way as manual betting. AFAIK, the server is unable to distinguish between bot and non bot bets. Verification should still be made however. It is harder for bets in automated betting to be verified due to the speed.

Betcoin.tm has existed for a fair amount of time. I believe they decided to do PR advertising more seriously here with signature campaigns and announcement threads.
Cloudbet have a limit on sportsbetting.

What is the maximum bet?
Maximum bets vary based on a number of factors. Generally, the maximum bet amount will increase as an event grows nearer and liquidity on that event increases. If you attempt to place a bet for greater than the maximum allowed your bet will be automatically reduced to the maximum allowable stake.

I keep a significant portion on gambling sites and the others in cold storage. Gambling sites are a great way of generating almost guaranteed profits due to the house edge. However, not all are trusted. I invest funds mostly in moneypot and the others in satoshidice.

For Bitcoin casinos, the system will automatically take a portion of the earnings for themselves during a specified time or when the user decides to divest.

For casinos that have POS coins, they can choose to also charge the user for their staked coins. Justdice does this.

That's what HTTPS certificates are for. When browsing using Tor, always ensure that there is HTTPS or the exit node will be able to see all the data.

For merchant, it is easy. Only a tablet is required for using the POS- Bitpay, Coinbase etc. Bitpay allows merchants to convert to fiat in a instance, no risk for volatility to affect the earnings. However, it isn't easy to do and there is not a huge adoption rate ATM. The general public are skeptical of Bitcoin and would avoid using it since it is too volatile. Merchants would be more reluctant to accept it after Bitpay started to charge.

They do download the block headers but not the entire blockchain. They take a few minutes to synchronise and take up much lesser space. For daily users, this is recommended.

I guess splitting the reward is the fairest method .

The network was not congested at all when this happened. The advantage of this attack is that little fee is required to disrupt the networks since the size isn't big. The blocks at that time weren't filled up at all in terms of size but were filled up with the number of sigops. Eg. This transaction https://blockchain.info/tx/9e451c7d53ca42a15b4e55ca67e7defc4d941959255ca6b960f010e623949b51. It doesn't require a high cost if network isn't paying high fees.

In a Bitcoin exchange, I would look for it's fees, features, solvency and customer support. In a Bitcoin exchange, solvency is most important. Mt Gox was insolvent for many months before it was public and there were still extremely huge volumes. This in unacceptable and an audit should be done frequently as a proof of solvency by a third party auditor like what Kraken did. Most exchange have to comply with the local KYC polcies and there may be delay. With a good customer support, the documents can be passed quite soon enough and would not turn off bitcoiners. It isn't acceptable to wait up to a week just for the verifications.

Multi signature is not a option to protect your Bitcoins if they are stored close to each other or signed on the same computer. A hacker can easily get both/all of the keys and hack your Bitcoin address. Paper wallet does provide more than adequate security if the generating device is virus free. They claimed that many were against the use of paper wallet but users can make several backup with BIP38 encryption on all of them. It is as secure as a Ledger nano if we were to compare that aspect.

Transfer all your Bitcoins into one wallet and use it. I doubt anyone would have lots of change even with HD wallets, change are also used when sending transactions. If there is indeed lots of different change address, transfer them into a single address and sign from there. It isn't hard to do.

This would only work if the user's wallet service/software allow users to sign message. Some shared wallets do not but some do, like coinbase.com. In that case, you need to ask the person to transfer them into an address which a signed message can be generated from.

There are people accepting gift cards at the currency exchange section. But be aware that the resell price is very low and hence you can only sell for around 80% of the original price provided that you bought it with cash and have the receipt (for most cases). Otherwise, localbitcoins have several people trading gift cards for Bitcoin but same condition applies.

I felt that I sounded rather pissed in some of my PM to you, sorry for that. My account is still too precious to be ruined, no reason for me to even default. Thank you for removing, I'll remove my neutral feedback too. Once again, my apologies.

There are tools which can help users to bruteforce the password. It would only help if user have at least some idea of the password or always use a well known phrase as the password. The tool is here: https://github.com/gurnec/btcrecover
