I heard about this gut, his story is unbelievably.

did you tried it ? :)

I was thinking the same thing
to change things in other things but does it really work?

have you ever tried this?
I do not know who to trade with?
I do not know with which thing I should start trading.

Everything is possible : ) i didn't try but it can be fun

yea, it could be fun ;)

I will think about it
if i do it i will post every step here
but I do not know what to start with.
example with a rubber ring

i am joking but it could work :D

what do you think about it?

I would search for something exclusive, like art, something old, or strange, and you can go to a street market and try to exchange it

yea

but I want to start with 1 Euro or something that cost under 1 Euro.

In that case is more difficult X )

yeah i know :D
