Securing your free “Bitcoin Cash” stash
In the last days of July 2017, the Bitcoin miners have unanimously decided to signal for Segregated Witness, ending a years long scaling debate discussion. However a few participants decided to reject this decision and create their own Bitcoin fork, Bitcoin Cash (also known as BCC, ABC or UAHF). As a result, all Bitcoin holders will be granted a new duplicated Bitcoin Cash balance (literally airdropped free money) if the fork activates — this post and the follow ups will describe how you can best secure this new balance, then decide to trade it, hold it or sell it as you wish.

Bitcoin security is more than multisig

Gone Forever: Bitcoin, AltCoins, Asset‐Tokens, & Death
If you died tomorrow would your family inherit your bitcoin, altcoins, and asset-tokens? The answer depends on you. While legally, the answer is yes, if your passwords, passphrases, and key locations die with you that probably won’t happen. Without those things your crypto-assets will be inaccessible. Like gold coins buried in a meadow; they may know the treasure exists but they’ll never be able to access it.

Bitcoin: Securing the Network
This white paper investigates how the Bitcoin network will be sustained, especially as its incentive structure changes in coming years.In the coming decades the mining incentive structure of the Bitcoin network is set to shift from block rewards to transaction fees. For this transition to be effective, the network needs to remain robust enough to prevent a 51% attack, while continuing to facilitate transactions at a low cost. Once block rewards phase out, ARK Investâs research demonstrates that a transaction fee of 1.2% would be sufficient to incentivize the buildout of a network that is secure from an economically profitable 51% attack, regardless of bitcoinâs market cap and the capital allocation of a nefarious miner. This 1.2% fee would underpin other potential transactions in the Bitcoin network beyond the bitcoin currency, which could include real estate transfers, venture capital contracts, and machine-to-machine transmissions.
