### Instruction:

### Response:
 Jake anaanza na bitcoin 80.
Anatoa mchango wa bitcoin 20, hivyo anabakiwa na 80 - 20 = <<80-20=60>>60 bitcoin.
Anampa nduguye nusu ya bitcoin zote, hivyo anabakiwa na 60/2 = <<60/2=30>>30 bitcoin.
Anazidisha mara tatu idadi ya bitcoin alizo nazo, hivyo anabakiwa na 3*30 = <<3*30=90>>90 bitcoin.
Anatoa mchango mwingine wa bitcoin 10, hivyo anabakiwa na 90 - 10 = <<90-10=80>>80 bitcoin.
