Do you think cardano will over take ethereum in terms of tech with voltaire being worked on this year. Along with erc20 converter for easy conversion to cardano via ethereum. 
That's still hard to come by as Cardano needs more support to lift its price near Ethereum. Cardano is currently cheap and you can buy it in large quantities and store it for a long time. But we know that anything can happen so if Cardano can raise its price beyond $1 or even over $4, it will be a surprise for us because we certainly wouldn't expect it, especially if the price could go over $10. Currently, Ethereum is still number 2 in the market and still leads the altcoin position but who knows what will happen in the future.
