One of the reasons why binance smart chain becomes this big right now is because ethereum gas fee is very high and this force some projects to switch to BSC but what do you think will happen once ethereum gas fee goes lower in near few months? Will BSC faced same fate as binance DEX? Or BSC will remain the better option over ethereum?
there may be many other alternatives to balance transaction costs on the ETH network, for example BNB BSc and even recently Matic polygon, some projects on the ETH network also have BSC and Polygon networks in their tokens considering that on the ETH network it is unlikely that they will looks cheap even though ETH 2.0 is implemented with a gas cost of 1 gwei it will look expensive at the current price of ETH, BSC and Polygon are not only competitors but can also be used as alternatives for blockchain projects on the ETH network can use other networks
ETH 2.0 only lessens the amount of transaction fee but won't make ETH network being attractive against Binance Smart Chain or the new kid on the block like Poly or Sol. So the transition from ETH to other smart contract networks will keep going. Binance Smart Chain will surely make some gains from this.
