can anyone please explain how to send btc from heatwallet.com to another btc address? what is the recipient? and into the "message" I just insert btc address ?
It depends whether you want to send BTC tokens that reside on the HEAT blockchain and are instantly tradable on the HEAT DEX, or genuine BTC that resides on the BTC blockchain and is accessible through your Heatwallet credentials on the client side BTC wallet.
There are several ways to send BTC, either genuine BTC or BTC tokens on the HEAT DEX. They're available for user logged into his HEAT account, depending on whether that particular HEAT account has funds in BTC tokens or genuine client side BTC wallet.
1. To send BTC tokens to a HEAT account, click on the top right menu -> Transfer Asset -> Insert receiver HEAT account number or registered email -> type BTC in asset and select the provided asset id -> enter amount - > enter optional encrypted message -> click Send. If some field is problematic the Send button remains disabled.
2. To send BTC tokens to a BTC address (your own or someone else's), click on the white Exchange (bar chart) icon on the top menu -> click the red "Withdraw BTC" button -> Fill in recipient BTC address and the amount. Click "Withdraw" and wait until fulfillment of the Withdrawal, which currently usually takes 1-2 days (quicker automation under implementation).
3. You can send genuine BTC that's stored in your client side BTC Heatwallet by navigating to your BTC wallet from the Wallet page (white wallet icon on top row) -> Click the Send funds icon on the top row (double circle), fill in recipient BTC address, amount and network fee in BTC (best fee to speed ratio suggested). The client side wallet transactions do NOT incur a HEAT transaction fee, so in essence the
secure multi-crypto client side storage (either through the web wallet
heatwallet.com or the
downloadable full node application is a free service.
