Well NFT was exist in Ethereum chain in the first place and NFT Community was big there so it's get more traction, Same with BSC Which is 1:1 ETH Copycat. People was also more familiar with Ethereum & BSC Network so i suppose it's normal.
And for this one, Thanks for the information. Bookmarked for now and will take a look later.

Binance is good but it's have limited staking option and the slots was always filled quickly so maybe can try some alternative like Pancakeswap which is the best so far where offering Pool with high return and various choices too. Uniswap was also good but current ETH gas fee was not worth if you farming under $1000 from my opinion.
I suggest using coinecko to see more details for Yield Farming, Coinmarketcap has some glitch in their APY indicator and their pancakeswap is still using V1 which makes it not updated and gives wrong information.

From my perspective, Compared to DOT and Solana, Avalanche or AVAX they don't provide any significant updates latelty and yes, as you said, only a few developers are active at the moment where Polkadot, which is my favorite, is intensively providing new Significant updates, on their chain More than 130+ Contributors on Github too which is have a Solid Community. It's a unfortunate that Avax isn't very optimal lately but I think it seems to be an internal (?) problem, Let's hope AVAX give us new significant update in the future.

I think it's depend on the "Meme" Coin/Token itself, SHIBA was successful because it was listed on Binance in the first place and get more attention from the community because of that, Every "Meme" Coin/Token out there always having a good concept but still it's need another factor like you said to become successful Community-Driven Project. Indeed investing earlier on Some ILO/IDO sometimes will give good chance to gain some profit but the hype was over and the market already full of it.

Well there is no other better choice though, Today the only reliable Meme Coin out there only Doge which already exist in the crypto space for the long time and have big community, Shib was good too but it's better to choose Doge since it's have better Volume, Listed Exchange and Bigger community. Just don't fall to another "Meme" Coin since some of them didn't have any real use case, It's better to use your funds wisely to invest on any project with real use case and better prospect.

Indeed, Meme Hype was over and so the bullish market too. The market was stagnant for now and i suppose there will be another bearish market, Bitcoin almost touch $30,000 and Ethereum already fall to below $2000, It's better to save the asset or maybe filling the bags by buying some Major coins like Bitcoin, Ethereum, LTC, ADA and stay away from any "Meme" Coin/Token.

It's just another Meme Coin without any fundamentals and that celebrities just shilling the coin same like Before, There are tons of new project like that creating new "Meme" Coin and basically you should be more careful since it can dumped anytime like some previous coin, Just stay away from that coin and invest your BNB or any other assets wisely. Good luck!

With the current source code that implemented on the Ethereum network, Triggering the smart contract was also need an Eth to pay the gas fee. Maybe in the future it was possible by only Signing the message? Or maybe implementing ERC865 https://github.com/ethereum/EIPs/issues/865 or EIP-1077 https://eips.ethereum.org/EIPS/eip-1077. I'm not an expert though but i suppose something like that right? Also for OP i will both of them for profit since it's have great potential.

Yeah anything can happens but Binance really doing great performance, Still remember about hacked Funds back then? Binance Anticipating this in a good way calmly and smoothly through an Insurance Fund that makes the community feel safer, Beside that they also have tons of other features like Launchpad, Staking, Futures, etc which is making Binance is one of the crypto exchange out there right now, Maybe later Binance will go bankrupt but I'm really sure the chance is very small, Well let's see what will happen in the future, Cheers!
