Choosing a website for trading Bitcoin Cash or purchasing cryptocurrency is not trivial and simple, because exchanges that are mostly centralized are estuaries of most decentralized projects.
The project is decentralized, however, the sound is centralized ("easily manipulated").
What happens is that many blockchain or crypto projects have financial problems because they have to pay dearly to the exchange for their token tokens, where these centralized exchanges "sell" to the blockchain project with volume or self-proclaimed data.
It's good if the blockchain project pays expensive listing fees, and then successfully gets a pool of investors or new token holders, but it turns out according to the existing research, many exchanges report untrue data.
In terms of crypto traders/investors, exchanges that manipulate transactions (fake volume) will have an impact on orders that are difficult to execute, even though the crypto exchange is seen (and promoted) is crowded and has many users, whereas, it may not be the case.
Interestingly enough, Binance, the company that recently bought Coinmarketcap, ranked first with perfect value.
Fake volumes from crypto exchanges and bitcoin trading websites have become very disturbing topics within the blockchain and trader community, previously CoinMarketCap had conveyed the bad implications of the misleading information.
Indonesia already has many crypto exchanges, many of which appeared in 2018-2019. Some are registered with Bappepti, others are still in process.
The following is Indonesia's best Bitcoin Cash trading website based on Coinmarketcap, but I filter only those that have been registered with Bappepti (Commodity Futures Trading Regulatory Agency) and accept the Bitcoin Cash market.
Indodax
Indodax.co.id is the first crypto exchange established in Indonesia, founded by Oscar Darmawan and William Sutanto in 2014 with the initial name Bitcoin.co.id. In March it changed its name to Indodax or Indonesia Digital Asset Exchange.
UpBit
UpBit.com is a Bitcoin or cryptocurrency exchange trading place founded in 2017 and a subsidiary of Dunamu Inc. in Korea, which is an application software company. UpBit began entering Indonesia in January 2019.
Luno
Luno.com was founded by Timothy Stranex in 2013 and was originally based in the United Kingdom. Luno has entered Indonesia since 2014 and has been registered with Bappebti.
Tokocrypto
Tokocrypto.com was founded by Pang Xue Kai in June 2017 and became the first bitcoin trading site to get a list sign from Bappebti. In May 2020 Tokocrypto announced that it was getting investment from Binance.
Rekeningku
Rekeningku.com was founded in 2017 by Fung Sumardy and Robbie Bun who have many Bitcoin mining servers in Indonesia.
Now that's in my opinion, a list of trusted and safe exchange websites that can be chosen as a cryptocurrency exchange that accepts Bitcoin Cash and is recognized by the government in Indonesia.
