Securest method of Bitcoin storage

[Devinitive]

Hello BitcoinTalk!

I'm new to Bitcoin development and I plan to invest more time towards development Bitcoin applications and services.

My first project is a Bitcoin Casino and it's just to dip my development toes in Bitcoin water. I'm using currently using the API provided by Blockchain.info.

Now obviously I want to keep the customer's coins as safe and securely stored as possible. I want to know is it more secure to create a new wallet for each new user/customer or to simply create one wallet for the site with a bunch of address for each user?
I understand that the second option is more practical, making the development process a little smoother.


Thanks!

Look into cold storage wallets

Look into cold storage wallets

And multisig wallets

i would suggest a backup wallet(a second wallet), in case the first got corrupted, 1 wallet only is a bit risky

Make 2 wallets, A hot wallet and a cold wallet. Keep a little amount of coins in Hot wallet say less than 1 BTC to pay for small withdrawals instantly but keep the majority of the funds safe in a cold storage wallet and you can do manual withdrawals.

This way even if a hacker hacks his way into the site he won't be able to access the cold storage funds. GL

hardware wallet huh?
How if I forgot where I put it?
that's may big problem...
use Hot wallet for small amount and cold wallet for big amount..

Yes btc trezor is good choince and what about few offline wallets from which you will send bitcoins when you will need and then you can throw them away.

A free alternative is to simply download the github version of bitaddress, boot offline linux from a CD-R and print a few copies of encrypted wallets (with at least 8-9 charachter password [don't store it on your PC, memorize it!]), I don't see a way how anyone could hack into those wallets or break into those wallets without obtaining the password directly from you (even if he steals the wallet, he doesn't know the password and you have another copy)

You'd still need to keep some coins in a hot wallet so you can process small withdrawals

Ledger is also a cheaper alternative, but Trezor is better I guess

Use Armory Multisig* or Electrum Multisig or Bither Multisig.

Bither Multisig helps you to use your mobile as one of the device and signing and transmitting datas can be done via Qr code. So it is pretty much secure than using a USB stick or other CDs for transmitting datas from on computer to another for signing and broadcasting.

* Correct name "lockbox".
