ACH takes like a week on coinbase and a wire still takes couple days when you want to use Fiat to buy BTC or ETH.

The cheapest as far as fees goes is to do the ACH transfer and wait about a week, which is terrible.
Then for the wire your bank charges you for the wire and still takes couple days to show up on Coinbase.

So, how do you guys buy your BTC and ETH so that you pay minimal fees and wait less time for fiat to arrive at your exchange?
Any other USA based exchange that is faster for fiat to show up or other ways I have no clue about?

Also, are you guys buying BTC or ETH when you want to buy Altcoins?
If you buy BTC and want to send to another exchange you end up paying a large fee sending BTC and it takes a while to arrive versus ETH which you can use for buying alt coins too,
so what is your choice for buying altcoins and sending to Binance for example? BTC or ETH

I appreciate your insight on this.
