It is true that investments can bring us income, but it can also make us lose. We cannot guarantee that investing will always bring us profit, so we need to have another main job in addition to investing.
Investment has two parts for profit and risk of loss, it is difficult to determine an investment with passive profit even gold is also at risk of falling in price during a pandemic and economic crisis conditions, but with regard to crypto investment I have no doubts to start investing when prices are low and determine investment targets for the long term use cold money so that we focus on achieving profit targets in the future.
