I'm grateful to have learned a bunch of things that I was mistakenly contented to be ignorant of:

• a bond is usually paid back all at once at the end of its term, while loans are paid back with regular installments until they are settled.

• notes are apparently how one should refer to bonds that mature rather quickly

• Bonds have a coupon, while loans have interest payments.

• I also learned from the El Salvador bad deal article that the coupon is applied yearly to the "nominal" (a term I learned from the first bitcoin bond paid in bitcoin)

  Now, the Volcano Bond pays you 6.5% interest, so you get $6,500 a year for 10 years. The Non-Volcano Bond pays 8.25% interest, so $8,250 a year for 10 years. So, advantage Non-Volcano.

I think I finally understand enough about bonds to begin understanding bonds.
