How many bitcoins did Jake have after the donation? ** He had 80-20=<<80-20=60>>60 after the donation
How many bitcoins did Jake give to his brother? ** He kept 60/2=<<60/2=30>>30 after giving half to his brother
How many coins does Jake have after tripling the number of bitcoins he has? ** So he has 30*3=<<30*3=90>>90 coins
How many coins does Jake have after the second donation? ** He then does 1 more donation and has 90-10=<<90-10=80>>80 coins left
