Tron has been growing in a tremendous rate this few months and with the massive dapps that is been integrated into the Tron blockchain I beleive Tron has a huge long-term growth . By investing in Tron now is a wise choice to do due to the fact that Tron pays huge passive income or its holds and investing in Tron dapps also increases your ROI.
It is definitely a wise idea to sell your car to invest in either Tron or steem because I see both blockchain as a retirement fund for investors @the4thmusketeer
My car is probably only worth about $4,000 after depreciation and all, so I probably won't be selling it, lol. But cryptocurrencies so far have made for great investments so far if you know how to understand the market movements.
