escrow necessary

cash deposit to any major national bank in us (not interested in paypal  zelle, or other bank linked method right now)

15% premium (markup for btc seller)

flexible purchases from $100-1500 necessary

if you buy btc from another hodlr (forum, meetup, ect) how do you check if coins are clean enough to send to an exchange ?  How to prevent buying coins that can not be used ?  Is there an oracle website bitcoiners can use to "check coins".  Whats is the correct process...does seller provide wallet address coins will come from so it can be checked before transaction ?

Many moons ago there was a block explorer like (blockchain.info) that displayed transactions like a map.

where can we find a visual block explorer similar ?

Basically this post is for recommendations - forex brokers/exchanges that allow customers to decide how much personal info is shared OR NOT. 

Withdrawal / deposit limits OK

This is a topic that keeps popping up but posts get out of date quickly.  Want to make a 2021 list of exchanges/brokers that offer forex, (crypto trading not required just crypto deposits and withdrawals) and of course have minimal history of scamming.  To keep thread short(maybe)  please do not recommend exchanges/brokers actively participating in kyc and aggressive blockchain tracking analysis programs.  NO USA BASED EXCHANGES.  Exchanges/brokers with separate usa and rest of world products are ok....like binance world and binance usa (except binance does not have forex)

(anyone know how to tell if the exchange you trade on participates in aggressive blockchain tracking programs more severe than basic wallet lists of bad people who may try to send evil tainted coins to an exchange )  Example: coinbase aggressively participates in blockchain tracking programs not just protect the exchange from receiving tainted coins


Any products or alt. coins that offer synthetic forex?  There are eur/btc jpyt/usdt eur/usdt(usdc) jpy/usdt, (think maybe there is xau/usdt) but dont know of any aapl/usdt, sp500/usdt or FTSE/usdt .  Please share exchanges that offer eur/usdt type forex but do not accept fiat or have separate accounts for fiat vs crypto deposit accounts.  Appears NO FIAT = No KYC 

BTC

Is this a serious thing?  freebitco.in/ - scroll down 1/2 way of page.  EARN INTEREST ON YOUR DEPOSITS section.

Just curious, didnt see anyone mention, but 4% daily compounded interest is kind of exciting if it is legit.....any one any info?
