5th October 2020, a crypto website Cryptowisser release an exchange list called Crypto exchange graveyard which shows almost all exchange and trading platforms that are gone scam in the note they didn't explain much except the platform's name, country, and when got scam.

But after one day they publish a press release on news.bitcoin.con and explain everything how and what causes platforms to go shutdown.

According to their report, crypto exchanges “die” due to voluntary shut down, hacking, scams, and being shut down by the government. While the scams and hacking are self- explanatory- the voluntary and government shutdowns as well as the mystery disappearances can be explained.

• Competition pushing out Crypto exchanges.
  Decentralized Exchanges push centralized exchanges out.
  Derivatives Exchanges see Growth.
  Non-Crypto Alternatives become more available.
  Regulations make it impossible for new Exchanges to survive.

The interesting thing on the list was Hotbit.io (which are popular among users) they said it got scam but it still live and working well. I use Hotbit.io for trading and had about $17 worth of Chainlink but after seeing the list I withdrawal all.

The list started from 2020-10-05 to 2014-02-07. You can see some name from the list below that shutdown in 2020.

I started using Coinswitch, and the impression was outstanding, so I thought let's share it and see what you think about it.

If you don't know, Coinswitch is an India-based crypto platform that allows users to buy, sell, and exchange over 654 coins via credit card for the world and via bank account deposit in India.

I compare it with LocalBitcoins (LB) and found LB is more expensive than CoinSwitch, where on LB the price was ₹909000 (minimum) while on Coinswitch the price was ₹825439 for buying BTC. And for selling BTC the price was ₹776,139 on LB and ₹814133 on CoinSwitch, this huge price gap and enough excuse to leave LB.

An also this price increase or decrease on LB if you change the payment method but not on Coinswitch and have payment method like Google Pay, PayTM, Phone Pay, UPI, and bank deposit.

I withdrawal XRP worth of ₹5000 and guess what I got my money in just 2 minutes in my bank account.

What you think it is better for long time use, I think so.

Here someone has written a CoinSwitch review. You can read this.
