One crypto user gave away at least $400 in Bitcoin gift cards to Canadian children over Halloween.

While many children dressed as ghosts, goblins, and witches last night may have been disappointed to find an inedible thin piece of cardboard left out in a goodie bag, a lucky few recognized the treat as a Bitcoin prize. 

According to an Oct. 31 tweet from Brad Mills, the crypto user filled a Halloween candy box with more than just chocolates and sweets — he also added $200 in Bitcoin (BTC) cards. Mills posted a video of him adding the two gift cards, each worth roughly 0.007 BTC following the coin’s rise to $14,000, and filmed the reactions of trick or treaters in his Canadian neighborhood.

One boy in a white costume was the first to meticulously dig through the box before saying to his group of friends, “I just got a $100 Bitcoin gift card!”

Someone else in the group retrieved the other card from the candy pile, repeatedly cheering “I got Bitcoin! I got Bitcoin!” leaving one of the two remaining children in chicken and sloth costumes to come up empty handed before asking, “What’s a Bitcoin?” Mills’ family later gave a few more BTC cards to a visiting group of girls who had heard about the crypto giveaway.

Though minors aren’t specifically barred from HODLing or trading cryptocurrencies in some countries, many exchanges still require verification to ensure its users are over the age of 18. As the children from Mills’ video are in Canada, they have access to Bitcoin ATMs, but most likely not local regulated exchanges to deposit their BTC or trade it for fiat.

Despite some of the children involved not understanding about the coins, reactions from the crypto community were positive, with many Twitter users stating it was a good lesson in scarcity.

“This feels historic,” said crypto statistician Willy Woo. “When these kids come into power there'll only be 0.002 BTC per person to go around.”

Other good samaritans have given away cryptocurrency seemingly in an effort to promote adoption. Cointelegraph reported in September that one anonymous benefactor distributed more than $1,000 in Bitcoin Cash (BCH) around the Californian city of Bakersfield “to spread awareness” among 'nocoiners' and 'newcoiners' alike.
