0.006BTC is a nice amount to start investing. If you have long term goals regards bitcoin and want to invest through DCA method, it's highly suggested you acquire a Ledger or Trezor physical wallet. You can order it online and receive at home. That is a simple wallet to setup, as there is a step by step tutorial, and very safe at same time. And next time, maybe you can acquire bitcoins from a direct trusted seller on this forum (P2P), so you save on transaction's fees which are pretty high for my taste in Binance (50,000 satoshis).
