One good reason why we shouldnt be supporting XRP is because it has the banking structure thats why it is very centralized coin,the supply is being manipulated by the founder and the developers which is why it is too risking to invest to this coin as we all know banking system is at risk as cryptocurrencies are going to replace the fiat system.
I do not understand your logic. Just because a crypto or platform is or is not centralised has nothing to do with profit. Would you rather invest in a sinking coin listed #950 on CoinMarketCap and be happy to lose your money knowing it was decentralised instead of buying in to a centralised project that clearly states its objectives and has a future?
If all your ethics and morals based around crypto currencies is about decentralised currencies being at the core then that is something for you and people who have your thinking. Those that purchased their XRP years ago for super cheap rates (such as myself) would like to keep hold of them. Just as Bitcoin hit $20,000 earlier this year, the same time Ripple hit a high of around $3.60. Western Union and several banks including one in the UK have trials running using the Ripple technology, just one positive announcement from any of those big companies that they are adopting Ripple in to their main business format then the price of this centralised project will rocket towards the $3 mark and beyond. The same cannot be said for the sinking decentralised crypto at #950 on CoinMarketCap
