That scenario is highly unlikely to happen. If a attacker gain access to the server, the attacker would only gain access to one of the key. To steal the funds, the attacker would have to go through bitgo's check. If invalidated, the attack will fail. Technically this is safe if done right. Eg. Keeping the third key safe in case anything happens.

Master public key is a key which allows users to generate a address but they cannot send it, most commonly used on web service to prevent coins loss if a hack happens. You can only spend it on the computer which contains the private seed/main wallet with the private keys. The seed can generate private keys and address hash however, the MPK can only generate public keys. Without the seed, no one will be able to get your coins even with your MPK.

That can be given by anyone even if they haven't trade with you before. Since this forum promotes free speech, mods do not interfere with the trust ratings and you have to get the person who gave you the trust to remove the trust rating.

Due to a forum hack that happened some time ago, the avatar was disabled due to security concerns. However, old members who had avatars before the hack will still have their avatar. Hopefully, we can change avatar in the next forum upgrade.

There is no accurate numbers so do take these for reference only. Since difficulty changes every two weeks, you would have to buy more hardware every now and then to ensure that you have more chance of actually finding a block. Varience would most likely affect your payouts, at times, the payout may be zero and at other times the payout may be more than expected. It will even out on the long run however.

If you have 0 connections, create a bitcoin.conf file at the data directory, find some nodes. And add this into the file, addnode=[IP] . Where IP is the IP address of the node. Try to choose a node that is closest to use. Use the link BitJack provided to find nodes close to you.

Because everyone knows bitcoin is not profitable, if a SHA256 coins become more profitable, the difficulty will rise very fast. Most altcoins now wants to be different from Bitcoin and have ASIC resistance as those who have ASICs would have more coins than those who dont.

True but you could also get backups from the wallet provider(most probably) online wallets like blockchain.info allows user to export backups. It can be a hassle to scan paper wallet everytime you use it and you would have a hard time searching for it due to its size.

Most of them don't understand bitcoin and they would naturally think that it is a ponzi scheme which will cause people to lose money or some operation to harass processing power. This isn't the case however, since the source code is open for everyone to review.

It's really just your preference, however, greenaddress does offer better security and features. Greenaddress allows you to setup a transaction limit and will limit your transaction volume. If your account gets hacked, the hacker will not be able to make more transaction than what you specified. Also, blockchain.info has some security holes before.

You have to give It time for people to discover and connect to your node. Anything above 8 means that you are currently having incoming connections which is already contributing to the network.

False positive happens nearly all the time, dont be alarmed if you see a virus on official files. Always make sure to check the checksums and download from the official site and you will be free from viruses. It would also be good if you could review source code and compile it yourself to ensure that it is free from viruses

Thats only for desktop wallets or if the OP has a backup. It is impossible if OP secured the backup with double encryption.

OP can try to contact support or the password can be reset by using the memoric phrase first seen when creating your wallet.

Great job for setting up the node.

Having a powerful computer would allow more incoming peers to sync and get blocks from you. The default max connection is 125. You can always allow more peers to connect by adding to your config where n is the maximum amount of peers to connect to you.

True but tor is more anonymous than open proxies. They are also easier to setup and require 0 trust. It really doesn't matter if 2FA is used as hackers won't probably crack your 2FA and password due to the automatic locks after a few failed attempts.

Xapo wallet does not allow the storage of our alt coins. You may have mistaken bits(0.000001BTC) for another altcoin. It is only a domination of Bitcoin like mbtc and satoshi.

Blocking TOR IPs is always a good idea however, if you are in a situation which you can only use TOR to access internet, you can't access the wallet as you have blocked the IP. If you whitelist and restrict IP, you would not be able to access your wallet if you go anywhere else and the network don't have the same IP as the whitelisted one. Do not do this if your address is dynamic as the IP will change.
It is better to keep a physical backup, if the email ever goes down or if your account gets suspended, you will be able to get them back.

Perhaps you don't understand what is a ponzi scheme. A ponzi scheme is a operation that pays you with the next person's deposit. They will pay you till people stop depositing and they can run away with your money or just don't pay you. Either way, you lose money.

That is a blatant scanning attempt, it is impossible to make 0.2BTC daily with any computer. It is just a well designed scam who target people who have no knowledge of Bitcoin. If it works, would the price still be $200?

It's actually sound like a ponzi scheme if customers can't withdraw and the company would just make up excuses. The company have been really shady in the history of their operation. I was required to verify my credit card due to me logging in through a proxy/vpn which I obviously didn't. I didn't bother to verify and my money has been stuck there since then.
