As we all know by now, cryptocurrency capital gains taxes are becoming a point of interest for governments tax organizations. Annoying! How can I minimize my crypto tax liability while staying in the good graces of the IRS?
I think if you are just exchanging your crypto in P2P or deal with someone near in your country you don't need to pay for tax and I think you can minimize your tax if you use fiat
that's incorrect. the OP has implied they are under the tax jurisdiction of the USA. all capital gains from cryptocurrency sales are taxable because it's taxed as property. like-kind exchanges also don't apply to altcoin trading, so every buy or sell you make (bitcoin or altcoin) is taxable.
one way to minimize your tax liability in the USA: if you mostly just hold for long periods of time, consider aiming for long term capital gains: if you hold for at least a year, your gains are taxed at a lower rate, usually 15% for most people. short term capital gains are taxed at your regular tax rate (up to 40%).
