ronenfe, you are free to create your own currency however you want. Obviously bitcoin is a good enough idea for all these people to be interested. If it had been created differently it may not have been as popular. Or perhaps your equal currency will be more popular. The beauty of bitcoin is that we are not forced to use it like the fiat currency the government forces me to use. You are free not to use bitcoin, and you are free to create your own equalcoin. Let us know how your new currency goes.
