For general altcoin are those cryotocurrency which are launched after the birth of bitcoin. In other word they are all those cryptocurrency other than bitcoin. Altcoin implies "alternative to bitcoin". I had published the same article at publish0x
After the halving of bitcoin RIPPLE and CARDANO is said to have pump more harder.
Launched in 2012 ripple is a sodtware based caompany which has its own coin. It was mainly mean for bank and financial instituitiom. It is a semi centralised permition blockchain.The main focus of XRP is to be able to do worldwide crossborder transaction. XRP solves the problem faced by SWIFT type of transaction making the transaction faster and time saver. The main masterpiece of ripple is to make bank used their sofware and choose XRP instead of SWIFT.
Till date many bank sector like SBI holding,Santander, Barclay etc have heard of tieing up with XRP. But haven't heard of publictly announced in large scale.
Ripple is now 0.19$ in market value
Cardano is a generation 3 DAAPS platform which is an ethereum based token.it is one of the few peer-reviewed and academically accredited project in the crypto space with over 31 different paper being published. It is the only project that focus on interoperability which is aware of multiple blockchain in the near future.it main focus is adoption effort on less financially secure country. It also makes decentralisation as a priority.
But the main frustration is how simimgly little they have accomplished comparing to how long they have been around.unlike ethereum they are not going to publish or announced anything officially until they compromise their quality. So all the cardano owner right now are 100% early adopter.
Cardano is now 0.0047$ in market value.
