Tron is the only cheap altcoin that's worth invest money on right now, gradually this blockchain network will expand in near future, that's certain, for the fact that it's still very cheap you can buy with very little money and hold for many years
Why are you so sure that the Tron blockchain network will gradually develop in the near future? Are you very close to the Tron Blockchain team? or is it limited to your personal guess? because holding Altcoin for years is also not certain that it will benefit someone.
