Say you wanted to invert hex colors so the stroke color is inverted of the fill color. Ultimately I decided against this and just going to use black for stroke. To do so using sed transliterate sed -e 'y/0123456789abcdef/fedcba9876543210/' you can't search for a pattern. So perl works in this case.
for f in *.svg ; do perl -p -i -e 's{(stroke="#[\w{6}])}{ ($new=$1) =~ tr/0123456789ABCDE/EDCBA9876543210/; $new }eg' "$f" ; done

Most people buy Bitcoin via exchanges, such as Coinbase. Exchanges allow you to buy, sell and hold cryptocurrency, and setting up an account is similar to opening a brokerage account—you’ll need to verify your identity and provide some kind of funding source, such as a bank account or debit card. Major exchanges include Coinbase, Kraken, and Gemini. You can also buy Bitcoin at a broker like Robinhood. Regardless of where you buy your Bitcoin, you’ll need a digital wallet in which to store it. This might be what’s called a hot wallet or a cold wallet. A hot wallet (also called an online wallet) is stored by an exchange or a provider in the cloud. Providers of online wallets include Exodus, Electrum and Mycelium. A cold wallet (or mobile wallet) is an offline device used to store Bitcoin and is not connected to the Internet. Some mobile wallet options include Trezor and Ledger.
