Buy a little in spot every month, in this cycle you won't get rich but at least you will be positioned for the next cycle

Good morning, I am a holistic beautician in Venezuela, with two daughters studying, one in high school and the other about to start university. Last week when BTC dropped to 112, I lost the 380$ I had managed to have in that cryptocurrency. I let myself be carried away by the noise and dreamed of the 125 that many said it would reach this month. I recognize that the first mistake I made was not educating myself well about this world. I have 20$ that I obtained from my work and I want to start over, and I want to do it on the right foot. What do you recommend while I manage to educate myself in this field? The expenses for education and the situation in the country make me see this world of cryptocurrencies as an option so that the money from my effort does not slip through my fingers... help please!!!!!
I am open to suggestions.
