Currently, TON Crystal tokens (Tons) and other tokens of Free TON blockchain are not available for sale or exchange to other crypto assets in Surf.
Free TON Community did not hold token sales, preferring instead to distribute tokens in exchange for contributions to the network. Throughout 2020, the project distributed TON Crystal tokens in more than a hundred contests and collaboration initiatives.
Nevertheless, TON Crystals are available for sale and exchange out of Surf. Let us refrain from mentioning the names. More information you can find at the Free TON Community channels.
