I would spend a lot of money to buy TRX and ETH instead of BCHabc or ripple. Tron will soon release version 4.0 and have a PoS system, which will increase the demand of the crowd. Besides, Tron also has a big opponent, Ethereum 2.0. I think 2020 and the years to follow will be a trend for PoS. Investors will no longer need to buy a GPU to mine coins. They only need to buy coins and execute the PoS program, everything will be very easy. then alts with good PoS system and generate higher profits will be more and more trusted by investors.
