What is Bitcoin and Cryptocurrency ? Part 1

A Look At Cryptocurrency and Bitcoin’s Colorful Past
Cryptocurrencies are digital currencies which are electronic in nature. They do not have a physical form like paper money or coins which you probably have in your wallet right now. You can't hold them physically, but you can buy things with them.
Depending on the merchant you're doing business with, they may accept more than one cryptocurrency as payment.
According to CoinMarketCap (https://coinmarketcap.com), there are more than 1,000 active cryptocurrencies right now. If you’re looking to invest your hard-earned cash but can’t afford Bitcoin prices right now, there are plenty of alternative cryptocurrencies to choose from such as Ethereum, Litecoin, Ripple, Dash, Monero, Zcash, and more.
We would, of course, advise you to do some in-depth research on the cryptocurrency you want to invest in as not all cryptocurrencies are equal. Some are more stable than others and would, therefore, make for better investments.
Bitcoin is not the world’s first cryptocurrency, but it is the most successful. Many have come before it but all have failed. And the reason for failure? Virtual currency had an inherent problem – it was easy to double spend.
You could pay $100 to one merchant and use the same amount of money to pay a second merchant! Scammers and fraudsters simply loved this loophole.
