charitable donations too ;-)
Charitable donations would be a great thing if you have bitcoin that has significantly appreciated and you would donate to charity anyway and you have other, additional income.
My understanding of the tax law regarding donating appreciated property is that you can take a deduction for the full value of the asset and do not pay any taxes on the gains that you had.
For example:
Suppose you bought one bitcoin for $10
Today that same bitcoin is worth $600
If you were to sell that bitcoin on coinbase you would owe taxes on the $590 in profits
If you were to donate that bitcoin to the redcross then you would take a $600 deduction on the value of the coin and would not owe anything for the gain
