If you are here you all know what is Crypto Currency and Bitcoin. But now Bitcoin is very costly we cant afford and time taken for transactions and fees for transaction are making a huge problem for consumers.
By taking this advantage Etherum was made by "Vitalik Buterin" to solve the transaction speed. Entherium changing to Proof of Stake Model from Proof of Work. But gas fees got a new headache for the crypto currency traders.
So these new "Tokens" are going to solve these problems and may get big than bitcoin, dont miss the boat now.
