Altcoins is an alternate cryptocurrency to Bitcoin. Once Bitcoin became popular, people realized the value, robustness, and flexibility Bitcoin brought and also started liking the fact that Bitcoin appreciated in value. They simply took the source code of the Bitcoin protocol available from GitHub repositories, forked it, modified it as per their needs, and created alternative cryptocurrencies. With the increasing popularity of Bitcoin, the usage and rate of Bitcoin have skyrocketed. Leaving that aside, the next question that arises is "how do we store or possess this virtual currency securely in digital form?".
