I think Luna is more better than Avax and very High potential like Terra Luna because they have their own Stable coin UST which is backed by Luna and most of Etherium Whales also holding UST which show that the future of Luna is bright. They are also constantly buying BTC in every Dip and I think thelis project can go big in Future.
now it also backed by Bitcoin that in few days ago continuesly done by their CEO. Luna has great potential to grwoth more than current condition , although alot fud coming regarding their stablecoin.no one will thinking only in less 2 years its price growth to more 100$ when i know it still around 0,5$.
Ethereum is still a pioneer in terms of smart contract platforms, and it will be very difficult to replace Ethereum,
look at Binance, even though Binance also makes a smart contract platform which they named Binance smart chain,
it is still very difficult to beat Ethereum, GAS Fee is cheaper,
but ecosystem Ethereum is much more because Ethereum has been around for a long time compared to BSC.
but Binance still has a big chance, why not choose for it?
maybe hathor could be the next ethereum competitors, with several main features especially on security and feeless transaction. if nano contract fully released and adopted , i am believe its ecosystem will growth alot .if compare with other smart contract plaform, maybe hathor be safest platform because its mined just like bitcoin.
