If my 8 year old child trades his Spiderman toy for his friend's action figure, is that considered income and is my son subject to taxes?

Update: Does he need to pay anything on his return?
Update 2: Serious question, since trading and earning Bitcoin I just found out was 'taxable income' if it wasn't received as a gift.

This isn't even considered money or currency, like what the hell is this....
Update 3: Trading assets has become taxable now?
Update 4: I'm not that old (19) so I wouldn't know about most things when it comes to taxation
