Making money online is a good idea. If we are unable too save much money from our day job than we need alternatives. Getting a second income from online work is start to increase our crypto holdings. For me the best way to earn some extra cash is through ebay. Selling old stuff from the basement which I don't need anymore can make a decent profit which can all go into cryptos.
And what if your day job is online? Should I look for alternatives offline?
In that case yes, it would be good. When u sitting 8h on your desk at home or at work - then you could work extra 2h for someone and do physical work. Instead of going 2h to the fitness centre.
I would still recommend proper exercise after a long work day at a desk.
Not every physical activity is equally healthy. It is important not to overdo it. Particularly if your muscles have weakened due to inactivity.
