Below is an instruction that describes a task. Write a response that appropriately completes the request in Swahili. Please answer in Swahili.

### Instruction:
Jake amasses a fortune of 80 bitcoin.  He donates 20 bitcoins to charity.  He then gives half of all the bitcoins to his brother.  After that, he triples the number of bitcoins he has.  Then he donates another 10 coins.  How many coins does he have?

### 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.
