please your advice will be of help
You should be saving at least 25% of your income/salary. If you are not, you should think of changing your job. You might need to change your city and move to somewhere you can afford. If there are adult depended on you, they should look for job to make some economic contribution. You can't have a second income if you don't have a supportive primary income.
If your primary income is providing you some savings, allocating a part of it to promising cryptocurrencies would be a good idea. Stock market can also be a good plalce to invest depending on the stock situation your country have. And if you have a good balance, buying a real estate in Tier 1 city is still a good idea, even if the smaller towns get empty, Tier 1 cities are bound to increase on real estate demand.
