What is the minimum amount to start trading in the coinbase spot trading? where I can find that info? and what are the differences of using coinbase regards other exchanges to do spot trading?
I don't use coin base, so I did a quick search and found the two pieces of information below.
What is the minimum trade size?
For BTC perpetual futures contracts, the minimum order size is 10 USDC and 0.0001 BTC.
For ETH perpetual futures contracts, the minimum order size is 10 USDC and 0.0001 ETH.
For LTC perpetual futures contracts, the minimum order size is 10 USDC and 0.01 LTC.
For XRP perpetual futures contracts, the minimum order size is 10 USDC and 1 XRP.
You can purchase as little as A$2 of cryptocurrency (crypto) and up to your account limit using funds from your account balance or debit card. You’ll receive an email notification to confirm that your buy was successful.
If you want to make a deposit, I am sure you will definitely see the minimum amount that can be deposited, and the difference in the minimum amount will depend on the asset you want to deposit. But I will advise that you should not go below $10. On Binance, the minimum amount you can fill your order with is $10 on their spot trading, and that's why I'm advising that you don't go below that on Coinbase.
The major difference to consider when trading crypto spots on other exchanges is whether they have all the pairs you want to trade and also the transaction fee. For Binance and Coinbase, the fee for spot trading is the same as 0.5%.
