The recent announcement that the CME Group would begin listing futures for bitcoin by year's end was viewed as a positive by many on Wall Street.

The ability for Wall Street firms to take a stake in bitcoin, without having to dabble in decentralized cryptocurrency exchanges, could introduce new money and reduce volatility. Futures trading will allow Wall Street to bet against bitcoin for the first time ever. It will also allow all walks of investors to borrow on margin to enter those short positions.

If bitcoin's value were to swing violently up or down, it could lead to a flood of margin calls that have the potential to destabilize the market for bitcoin. And because there's no precedent for an asset like bitcoin, setting the margin limits is nothing more than guesswork at this point.

Since bitcoin's inception, individual investors have controlled its value. Compared to Wall Street investment firms, retail investors are far more prone to allowing their emotions to influence their investing decisions -- which rarely ends well.

Also called block withholding, a pool may use their computational power to mine a block and then hide it from honest miners instead of broadcasting the new block to the network. The selfish pool then attempts to find the second block while the rest grope in the dark.

If the greedy miners manage to find a new block before the other miners, then broadcasting the two blocks makes the forked chain the longest. The selfish miners will be ahead of the other miners, getting all the rewards. Such conspiracies, on a large scale, can be combined with the Sybil attack to cause considerable harm to mining because selfish miners can then use their power to invalidate transactions on the network.

Although reinforcements have been instituted to mitigate this severe concern, fears still abound concerning this transaction risk to Bitcoin. Bitcoin is becoming increasingly sturdier against coordinated double-spends. However, some people might still be able to constitute attacks that would make them benefit from using the same coin twice in the same transaction.

Irreversibility then makes it pointless for Alice to get the transaction invalidated. And there is no recourse because Bitcoin is unregulated. The so-called over 50 percent or 51 percent attack is a security concern for Bitcoin though not one that is easy to carry out.
