Bisq has very poor liquidity in non-euro/usd markets.
nostr:npub1dllf8wmj6jk83r7chck6madmfgh3fges65ctpe5t6ueujazvvcvsh20tz5 is a decentralized Bitcoin exchange that allows users to buy BTC with pretty much any fiat currency in the world
As for custodial wallets, those should be avoided because they are centralized and compromised
Best to only use non-custodial wallets
As for hardware wallets, Jade hardware wallet is a decent choice
Avoid Ledger hardware wallet at all cost.
Ledger is compromised, it does data mining on its users
Discussion
The liquidity is good enough for people starting out.
Also, that’s perhaps the premium you pay for using a platform that is decentralized and censorship resistant
The OP listed India, I've looked at the INR market quite a bit. Some years ago my order was the only order for several months before I gave up. Recently I've seen about 1-2 orders a month. That's not beginner friendly at all.
Also in Euro/USD markets, I see smaller amounts (< €100) often have close to 50% premium. You get more reasonable, say <10%, premium only if you are willing to go to above €400, again not so beginner friendly.
I found Peach Bitcoin a lot more beginner friendly when trading in Euros.
