If I buy the token now, per token will cost me 0.12 USD. What could be the price after listing? I have seen some message which says BittWatt token will trade in 3 digits by 2022. Is this possible?
let me have a look in my glass orb

Noone can tell you the value of the token in the future, if you think the price will drop after listing on exchange, you can place low valued buy orders to get some cheap tokens, BittWatt however looks quite promising and I doubt the price will go much lower than the first buy offers that will be placed on the exchange
haha, yeah we'd all be millionaires if we could tell the after ICO price of coins

Look at it this way, they're making huge progress with the partnerships they are establishing, however lets be realistic, 3 digits is a long way off if you mean it'll be in the hundreds.
