Ahora leyendo el post de trybe https://trybe.one/hard-day-at-the-office-what-happened-with-the-trybe-airdrop/ entiendo lo del "ocultamiento":
The simple fact of EOS is that unlike many of the blockchains before it contracts and values are mutable — this means that they can be changed. For those where the primary appeal is that a coin or token is irreversible and forever yours… or forever lost…then there are some ways to do that on EOS, but they won’t be universally adopted.
