Absolutely. In fact, there are nearly 2,000 of them out there, with nearly 100 new ones being created each month. This was made relatively easy with the development of the Ethereum blockchain and the ERC20 smart contracts that allow the simple creation and operation of digital tokens, or cryptocurrencies. In fact, there are a number of sites that can take care of all the tech stuff for you.
The problem, however, is not can you create your own coin; you clearly can. Instead, it comes down to the value that your coin will have. Put another way, let’s say that you create your own “MarkoCoin” and issue yourself a billion of them. Congratulations! You’ve started your own cryptocurrency. But now what exactly do you plan to do with your MarkoCoins? No one else is going to buy them (why would they?) You can’t use them to pay for anything (who would accept them?) In fact, all of your billion digital coins taken together will have a value of…$0.
Now, if you have a plan to somehow make those tokens valuable to other people in some way, then it’s a different story. You will need to write up a White Paper to explain what the coin will do and why it will be valuable, pull together a team of technologists to implement the coin for you, and then spend about a million dollars in marketing before you launch your Initial Coin Offering (ICO), which is when you try to sell your coins to other people.
But at this point, since over 95% of the coins that people have created have proven to be either outright frauds or completely misguided and useless, many of the people who might have purchased a new coin a year or two ago are now sitting quietly on the sidelines.
So, the answer to your question is “yes, but…really?”
