What is virtual money
Virtual money is called conventional units, which are represented as records in different electronic systems. All transactions usually occur using the power of the Internet, but sometimes you can dispose of electronic money using a mobile phone. Each user can exchange electronic money for cashless or cash at any time. This service also involves opening your own electronic account in a few minutes and absolutely free.
No one will say exactly when the electronic money appeared! This happened unnoticed, as there was a need to pay for services without leaving home. And, undoubtedly, in the near future, electronic money will acquire a single world-wide character.
Payment for services with virtual money is a bit like a method of calculating a regular check, but you do not need to sign by ink, but with an electronic code and a password. This method of payment is very convenient, since virtual money is instantly transferred to anywhere in the world, and almost all financial transactions can be made without contacting the bank. The relevant software controls the correctness of the transaction and pays for the purchase within a few seconds.

theres a lot of definition of virtual currency or what we called virtual money.. some says it is a unseen currency but can legally be used in payment method some says it is future currency etc. and yes every opinion and own definition and understanding are all true. virtual currency is unregulated digital money BUT still not the same as a digital money itself. because virtual currency is controlled by its  developer and not by the government while digital money is what we all have in our bank ( by using our debit and credit acct.our money becomes digital and paypal as well is considereds as digital money as we all know that ofcourse.) so that is why virtual money most of the time people think that it is illegal and can be easily used by criminals because it is not under government not even release in central bank..but still people whp knows what virtual money is.. still using this as a LEGAL payment method.

Virtual money is money that can not be grasped. It has no specific physical shape and is used in an electronic environment. Virtual money is usually used to make payments, made services through the internet (with user and password). This method is extremely convenient for the growing economy as today, used by many people. I am confident that this virtual currency will grow more and more because of its popularity and convenience.

Virtual Money can be defined as a digital representation of value that is issued and controlled by its developers, and used and accepted among the members of a specific (virtual) community. Unlike regular money, it is relying on a system of trust and not issued by a central bank or other banking authority.

Virtual is defined as having no basis of physical reality. This virtual currency has
born and defined since 2012. Virtual money is almost the same as regular banknotes. But virtual money is invisible but has value, so it can only transact using the internet network. 

Virtual money is commonly and easily identifiable as a representation of fiat in digital form. With modern technology
and the internet, online transactions are much more faster and convenient. It's a growing trend and since were all
hooked to screens, phones and portable devices. Crypto and digital money is just an extension that complements the
technology and rising trend. It's now a universal standard in online and digital transactions and investments. It's money's
innovative contribution or response to the evolving digital age and movement.
