Now we have Paypal entering the crypto space and honestly I am not sure why Paypal will not introduce XRP to its 286m worldwide customers.

Ripple CEO Brad Garlinghous said in a article 'no keys, no withdraws' to show his disbelief. 

Just in 2nd Quarter Paypal had $220 billion worth of payments being processed.

I will not be surprised if we see introduction of XRP by time of launch next year.

Remember that not all metamask user is using Uniswap or other DEX that needs extreme transaction speed in case of network congestion. The reason why they might not save the gwei is because they are making sure that people will not mistake on using higher fees. If a user want to transfer fund during congestion and want the transaction faster than the default fasted. They will manually adjust the gwei but what if they will send again in normal speed but forgot to change back again the gwei in default? It will cost 20$ ~ 50$ for a normal transaction if the feature that you want implemented.

In addition, it should be implemented on the side of the dapps, in this case, to the Uniswap themselves, it is true that it could incur your fees on normal transactions outside of the uni swap when this feature was added. And what disaster it could get further is that transaction fees on Ethereum will be high as people always choose the option to send the fastest transactions on the main net, as a result, it will be like bidding, the higher the fee, the faster it would be transferred. They have already set the standards for the most efficient way of managing the gas, I think that is enough and it is on our end to adjust.

Sometimes the fastest option of metamask is not enough when you are trading on uniswap. So we have to add some extra GWEI so that miners will quickly process our transactions. It's so that we can beat the queue and get into token asap.

I think metamask helped me to cancel the previous transaction because of the low gas costs, so I can add gas fees by canceling the previous transaction, you won't be able to do that if you use myetherwallet, so I think that feature is good enough for metamask users and you only need to see ethgastation to see and make arrangements for the gas costs needed

Well, metamask already gives the user 3 different gas amount options, fast, faster, and fastest, why did you choose to put it manually ?
Have you tried to choose the 'fastest' gas fee ? We can compare the amount of gas fee on metamask with gastracker in etherscan website.
Till now, i have no problem in using metamask wallet to send eth or tokens.

Looking ethgas.info to know more with your gass setting transaction, you must match between ethgass.info and with your gass setting on uniswap or sending your coin in metamask. They will three kinds transaction way, first most faster where you need pay higher fee and you can use starndart with normal fee and using cheapest for lower fee but your transaction take long time for receiving. I use second way when sending coin from metamask, myetherwallet to get lower fees and look faster than third way for sending coin.

Right here! I always consult gwei and gas price before making a Tx to choose a suitable one. Do not use tools on metamask, it always have low gwei and gas price is too high, it is not suitable if you want to send transactions on ETH blockchain.

this is a very funny question. ripple has very high supply value. the amount in circulation is increasing day by day. maybe it will not even reach the highest value. but it will never see $ 5.

yes you say, but it needs to be emphasized that the agreement is not a swap agreement, not a transfer agreement at will without us agreeing to it, it still needs a second agreement to be done, and when we close the browser, the connection will automatically be lost?

In the past months, malware infection attempts on this forum has become increasingly sophisticated. Below is a summary of infection techniques that I have encountered. With the most sophisticated attacks, common sense and virus scans is no longer sufficient to ensure safety ................

Be careful with remote access to your PC
Don't use VNC to remotely access your PC. Passwords are easily brute forced via automated scanning scripts. For best security consider two-factor authentication.
