There are many sites to earn money but the best for me is Toloka yandex they keep giving tasks and in different languages, other sites I use adbtc,starclicks,coinpayu,timebucks,ysense,idleempire,swagbugs.but you have to take into consideration that tasks in most of sites depend on the country you live in, some tasks are available in one country and not in another which make it good for people and not good for others. but the best and number one is toloka yandex.
