No one can set a fixed income on investing in bitcoin or crypto. They can only set goals about how much profit is achieved. even, when the market is red like now. No one can guarantee the loss. Not to mention income from profit. Depending on the time of the market to plan or target.
Trade is not a profession that can estimate a steady salary monthly, you can take up to one year or more years to receive profit from the business. However, if the profit can be up to more than one year in the field, I am sure that the profit is not small, it is a lot and worthy of what you have been waiting and work for the time you spent to trading.
trading is still a profession because there are people who actually study hard in order to learn and master it.
trading isnt an easy job , that is why many people need to attend a class or a seminar regarding on trading , so that they can improve their skills , knowledge and the most importantly to control their emotions. but overall , bitcoin trading wont give you a fixed salary or income due to the reason that the market of cryptos are too volatile.
