Just so its in 1 location that can be referenced..
1- Get the apps "Coinbase, Trustwallet, and KuCoin"
2- In Coinbase convert $$ to Bitcoin. (Note they put a hold on bank transactions. Mine seem to be 8-10 days)
3- Send the Bitcoin to KuCoin
4- Convert KuCoin to BNB. (You will need to transfer from your main wallet to your trade wallet to do so)
6- Transfer BNB to Trust Wallet
7- Convert BNB to SmartBNB
8- Convert SmartBNB to SafeMoon. (This one is tricky because you gotta go into your phones web browser and type trust://browser_enable in order to get a browser button on the Trustwallet. Then you can hit the browser in the TrustWallet app and access Pancake to do the swap.)
-edit
Some people may be able to just buy BNB in TrustWallet so you can skip steps 2-6 but the payment system that handles that rejects me and many others. I only know 1 person that was able to get some through that way and they could only buy little bits at a time.
