To get the coins without investment and mining I used cranes, also participated in the company's bounty and airdrop
cranes have not been working for a long time and it is already impossible to make money on them. only if some penny. but the best thing now is to participate in bounty campaigns if you don't have money to invest
Earnings on cranes are minimal, if not minuscule. And be careful, many of them do not pay at all or set such conditions that waiting for payment is not enough for a lifetime. Use only proven sites. Freelance sites and platforms give more possibilities to earn cryptocurrencies and start from zero. Some bloggers (popular people already) earn crypto on donations... and its works well.
