All those hype about Solana is only due to the fact that there are multiple airdrops that are happening in its ecosystem. People love airdrop and that is why everyone wants to buy Solana. Another factor which is driving the hype are meme coins success in its ecosystem. Apart from these two factors nothing make Solana a blockchain to look forward to. I think you should do your own research on Solana and then decide whether you want to invest or not.
Before these airdrops and meme coins came in Solana, the coin is already popular because it has a good background. They are like a bonus only for those who believe on the coin's potential, especially during their darkest times. Not all loves airdrops because they are not lucky to get rewarded and even if they do, they are not satisfied with it.
Also, airdops are from tokens under Solana and not the coin itself, so it's not the one that they will be buying. Meme coins on the other hand, have no real direction, so it's kinda odd if we call them successful. Solana already proved its worth over the years, so it's definitely one of those cryptos which are a must-buy.
