Write a compact guide for buying DVC tokens in Stellar DEX - 70k DVC

[DevElCuy]

There is already an extensive guide split in two blog posts:

1. https://peakd.com/devcoin/@satoshi0x/how-to-buy-sell-dvc-using-stellar
2. https://peakd.com/devtome/@satoshi0x/part-two-exchanging-your-dvc-tokens-on-stellar-for-blockchain-dvc-coins

The compact guide should teach the user to:

1. Register in https://interstellar.exchange and create a wallet (if user hasn't any stellar wallet)
2. Import an existing wallet into https://interstellar.exchange (if user is not registered in interstellar)
3. Fund the wallet with enough XLM tokens
4. Trade XLM for DVC tokens from https://interstellar.exchange/app/#/trade/./DVC/GBHAQ252S4Z4AQOM4BWIRC3UHAOJIKCZQBUJGD336YH2O7W2NKRXMHA5/XLM/native
