It doesn't really matter whether you believe Venezuela is a democracy or not. For an investment look at the governments financial track record.
If you want to crowdfund Maduro regardless of human rights issues, fine go ahead, but you will lose money on this "investment" for sure.
Maduro's personal human rights record is clean. Unlike every US president in the last centuries who has personally ordered invasions, bombings, terrorism, psyops, coups etc. If it was for human rights nobody should invest in anything in the US.
Maduro is an elected President who's gone through a media assassination because the US need to overthrow him (as they tried with Chavez for years), as simple as that. His government has faced the worst siege and aggressions (criminal, financial, commercial and through the mainstream media) a country could get. The information on Venezuela and Maduro is a pure childish caricature, written by Venezuelan opposition, that is funded with millions of dollars by the US (meddling in elections?).
In 2017, 176 people have been killed by the extreme violence initiated by opposition funded gangs in the streets. The opposition ordered to "take the streets' in order to overthrow the elected government. ANY government in the world would have done whatever possible to keep peace. They successfully did it, with the election of the Constituent Assembly that sentenced the political defeat of the opposition violent strategy.
As for your opinion on the investment, well. It's a quite poor.
