token sale is exclusive for ETHEREUM and ERC20 wallet only?
how about some people who want to participate using bitcoin?
they will sell drones and other relatated products soon, bitcoin and etherium tokens are possible to use if you want to use Deep Aero services...
You can only buy at their token sale using ethereum so if you have a bitcon or altcoins you need to exchange it to ethereum before you can buy your deep aero token as stated by them.
This has been done to safeguard contributor/investor interests. In the unlikely event of DEEP AERO ICO not meeting its softcap, funds will be refunded to contributors. The company will not be able to use these funds. This has been enforced by the ERC20 smart contract.
You will have to convert BTC to ETH and then buy DRONE tokens.
even if they don't reach their target cap or they fail you can get your invested ethereum back to your eth address
