On May 13, cryptocurrency enthusiasts were pleased to hear that major retailers including Whole Foods, Lowes, Petco, Regal Cinemas, and Gamestop will accept payments in crypto. The payments will be processed by Flexa using its custodial wallet called ‘Spedn’ which gives people the ability to spend with bitcoin core, ethereum, bitcoin cash, and GUSD.
Ripple is a technology that acts as both a cryptocurrency and a digital payment network for financial transactions. The coin for the cryptocurrency is premined and labeled XRP. ... XRP is a currency on the Ripple blockchain. Here's the kicker, though: Institutions using the Ripple blockchain aren't required to use XRP but European and North American institutions do.
Ripple gave a lot of millions in XRP away to charity . Ripple gives away $29 million of its cryptocurrency to public schools,,Ripple Announces $105 Million Charity Venture for Education, Financial Inclusion Projects..and a lot to Ellen wildlife donation,and so on..did they sell it..guess so
51% AttackA 51% attack is when a miner, or more likely a mining pool, controls 51% of the network’s computational power. With that ability, they could invalidate valid transactions and double spend funds. They’d achieve this through creating and confirming their own fraudulent blocks, and do it so quickly, the rest of the mining community creating genuine blocks would have their legitimate work invalidated.That’s where PoS could really help. Even if someone owned 51% of a digital currency, it would not be in their interest to attack something in which they have a majority share. Also, it’s very unlikely that anyone would be interested in buying up 51% of a currency, due to it being prohibitively expensive. According to game theory, those with a larger stake in a cryptocurrency should want to maintain a secure network. Any attack would only serve to destabilize the digital currency, diminishing the value of their stake.
PoS would be a more fair system than PoW, as technically anyone could become a miner. PoS offers a linear scale regarding the percentage of blocks a miner could confirm, since it’s based on that person’s stake in the cryptocurrency. That means someone with ten times more coins (e.g. - $10,000 vs. $1,000) would only mine ten times more blocks. Under PoW protocols, spending ten times as much money on mining hardware will produce higher computational power logarithmically, allow for more equipment due to the nature of reduced prices when buying in bulk, and might provide further advantages since highly expensive equipment often functions exponentially better than less expensive counterparts.
Until recently JPMorgan CEO used to claim that Bitcoin has no "intrinsic" value. And now JPMorgan says that Bitcoin is trading above its intrinsic value. In crypto don't believe any information without doing your own research #bitcoin #cryptocurrency

Of course, it will grow, that's not my point, my point is, why is world crazy after Bitcoin.. I mean I understand it's the first cryptocurrency and earlier there were very few alternatives to Bitcoin, but now we have so many cryptocurrencies!!
The way I see it, cryptocurrency are the currency of internet, millions of people using internet will use cryptocurrency to exchange goods and services in future just like Bitcoin is used on darkweb!.. The only question is which will be the currency of choice?
