Cryptocurrency is legal or illegal.

Their are two different things.

Cryptocurrency being legal & Cryptocurrency being allowed as a legal tender.

Is Cryptocurrency legal?

yes!....Why?

On 6 April 2018 in India,

RBI imposed a banking ban on India banks to have a relationship with crypto companies.But the same banking ban which is lifted in 2018 by a suprim court decision,Indias supreme courts allowed banks to handle cryptocurrency transactions from exchanges and traders, overturning a central bank ban that deals the thriving industry a major blow. & because of it the Indian bank also allow to have business relationships & banking services with an exchange. Then whats conclusion, trading on cryptocurrencys as on date is absolutely legal.Then whats the problem? ,Problem is that Cryptocurrency is an illegal tender of money. What is BlockChain?

It is simply combination of block & chain. What is block:

Block is nothing but database which stores a lot of information.No of transaction takes place & those information gwt stored in block. Ones block is full another block comes into picture.When this block starts it will pointout to the last transaction(second block basically pointout to the last transaction).Third block will also pointout to the last transaction of the second block.Now all these blocks will be linked or tied together with the help of a chain & these concept called as BlockChain Now their is question, if we want delete the data from one of the block, is that possible?..NO,why? Because third block was pointing out to the end of the second block if second block if second block goes away it will be easily understood that something is missing, so this can not happen.that's why the blockchain is immutable(unable to change). What is Bitcoin?

Their is no intermediary during transaction, then who will verify this transaction? Their are thousands of people all over the world who will verify this transaction? Their are thousands of people all over the world who are wanting to verify this transaction these people are called miners.Whenever a person sends bitcoin to B no one say that in plain English that will be written in some cryptic language.These miners who are all over the world they will try to solve computational problem, very powerful computers(super computers) they will require to solve these problems.once they solve these problems, they will get something in returns as reward that is where we say they are mining the bitcoin.
