Can I buy A2A tokens by BTC or other cryptocurrency instead of ETH?
A2A ICO will probably only allow ETH.
No, I don't think so. In whitepaper, they told us that they will support btc & other currencies

From the Whitepaper:
Also, you can buy A2A tokens with Bitcoins, Dash, zCash, Ripple using instructions
on the https://stex.exchange/ico page. Tokens can be credited to your STeX
account or to your Ethereum address.
