EAs are coded to follow technical analysis so they might require monitoring too during the high volatile periods and if you aren't familiar with the coding/programing then you have to be very careful during these times.
If we can practice and develop the right skills to make money we can get it coded in to an EA and make millions of millions in money however depending on someone else might not help. It may only be day dreaming of getting the holy grail and start making money over the night.
Coinbase is a renowned name in the digital asset trading industry. There were many exchanges which also served the bitcoin industry however they are not here anymore, either sold out or went out of business. Some other names which are still in the industry are binance, lmfx crypto etc.
I don't go for mining or any other apps for ROI, i prefer trading to make some extra money. Moreover, the bitcoin hype is over perhaps will get attention again when it creates another ATH again.
Agreed since earning profit is the goal of every trader so if the trading objective is reached, better take the screens off and go have fun with family or friends rather than dweling into the topics which only create mess like thinking who is who.
Reputable brokers like HFM, octa, xm, exness, lmfx etc does not make money out of trader's losses instead many of them have traders educational plans so that the traders can learn and earn.
Leverage can be helpful in making more money however using high leverage while you still learning about the market can lead to losses so choose leverage wisely and keep it low in start.
