OP, the buying back system is the strategy which works effect during the year 2016 and it won't work in this present market the concept, experience of the team with community support play a vital role these days. You can go for BNB but I will advise not to invest in it for a long term.
I think burning a coin is not an indication that the coin is promising. Because in this case, the rise in the price of a coin does not occur as a result of an increase in popularity and demand, but due to a decrease in the number of coins in circulation.
Burning of coins surely doesn't mean the coin will thrive in the market but increase in popularity and demand of coin will definitely make a coin surge in price since the level of demand are what determine a price of crypto in the market. An example is BSV despite the creator is not Satoshi newbie still fall for the hype he used.
