Most often, such coins appear on decentralized swaps such as UNI, 1inch, where investment in such projects is simply outrageous.
It's caused by those meme tokens can't be listed on exchange site instantly.
What can you advise me on where to find cheap new, interesting meme coins?
You should move from ethereum blockchain. The majority of meme tokens were getting deployed in the BSC chain and they are moving from ethereum due to the non sense fees. If you wanna find a new meme token that being launched in the market and BSC is your answer. It will always be launched on pancake swap. The fees on ethereum blockchain is not affordable anymore by the small traders.
Perhaps there are many of them on the BSC or Sol network? Perhaps similar projects also appear on other blockchains, which allow transactions to be carried out instantly without huge commissions. For example Near or TRX?
Yes for BSC but i rarely see that on SOL network. Forget about near and TRX. These were bad blockchains.
