THE CHAIN COIN DUMP AND HODL CREW IS HERE! THE DUMP AND HODL CREW! WE COMIN’ AT CHEW! Lower Fees: There aren’t usually transaction fees for cryptocurrency exchanges because the miners are compensated by the network (Side note: This is the case for now). Even though there’s no bitcoin/cryptocurrency transaction fee, many expect that most users will engage a third-party service, such as Coinbase , creating and maintaining their own bitcoin wallets. These services act like Paypal does for cash or credit card users, providing the online exchange system for bitcoin, and as such, they’re likely to charge fees. It’s interesting to note that Paypal does not accept or transfer bitcoins.

There is no other electronic cash system in which your account isn’t owned by someone else. Take PayPal, for example: if the company decides for some reason that your account has been misused, it has the power to freeze all of the assets held in the account, without consulting you (Trust me, this has happen to me many times) It is then up to you to jump through whatever hoops are necessary to get it cleared, so that you can access your funds. With cryptocurrency, you own the private key and the corresponding public key that makes up your cryptpcurrency address. No one can take that away from you (unless you lose it yourself, or host it with a web-based wallet service that loses it for you).

The input script is known as the ScriptSig as it is the script containing the signature. is the unhashed public key and is a ECSDA signature derived from the private key. The output script is known as ScriptPubKey as it is the script containing the public key where the Bitcoins shall be spent. is the hash (SHA256 and then RIPEMD-160) of the public key, which is a Bitcoin address ( if this is confusing to you, please read the Bitcoin wiki on Bitcoin Addresses and Elliptic Curve Digital Signature Algorithm before proceeding).

This mostly stems from the fact that you generally can’t use a cryptocurrency without also being invested in it. I may hold $1000 in a credit card, but I don’t own any shares in Visa or Mastercard. However, when I hold $1000 worth of bitcoins, I inevitably own a part of the Bitcoin economy. As its value rises and falls, so too do the coins in my wallet. While this also is true for real-world currencies, their market cap is so far beyond us mere mortals that we can’t really hope to influence it in a significant way. Cryptos are still fledgling economies where each person could make an impact.

Because blockchain is a distributed database, it operates like a spreadsheet that is duplicated thousands of times across a network of computers,” which the network keeps constant tabs on and updates. This way, there’s no single or centralized source of information the way you have with the Googles and Facebooks of the world; it exists in a public and verifiable forum of millions of computers simultaneously. In October 2008 the world was in the midst of a global financial meltdown. Stock markets had hit historic lows, banks had failed and billions of tax dollars were spent on bailouts.
