hey guys im a bit new to this im wondering wich crypto is the best to start with if i wanna mine... my graphic card is a Nvidia gforce Gtx970
If you want to mine for fun and also have the satisfaction of watching the number of coins appearing our of nowhere, try mining SiaCoins with that GTX970.
But take note that SiaCoins worth extremely little now. Maybe if you keep it for a few years, it might worth something.
If you want to mine something that is worth more, then try to mine Ethereum. But you will mine a long time (months) to get a tiny fraction of a token. But that tiny fraction is also worth something given the prices of ETH now is about US$308/ETH.
Go ahead and try it to understand how it works. That is how we all learn.
