Hi everyone so quick questions out of the 100+ platforms to trade coins on.
Are there some you would say need to watch out for? Or are they all truth worthy?
I would watch out for most of them and stick to the reputable exchanges. Bitstamp, Gemini, Coinbase/GDAX and Bitflyer are all licensed and trustworthy. With Bittrex's recent issues (accounts being locked, new KYC policies and lowered withdrawal limits), Binance has quickly become the most trusted altcoin exchange.
That said, I would spread around the third party exchange risk and not keep all my eggs in one basket. Any of these services could be hacked and immediately become insolvent.
Some of these verification processes take forever. I guess it's best to sign up on all 100 maybe and wait it out until verified or the right time comes?
I remember when I first got into Bitcoin. This was my mindset as well. The truth is that a lot of these exchanges are pretty shady and I'd rather not give my ID to them. One or two exchanges like Bitstamp or GDAX? Fine. But I'm not giving my passport and SSN to random shitcoin exchanges. That's asking to get your identity stolen.
I've noticed last week on coinmarketcap.com there was 1,372 coins, then 3 days later 1,380 coins, then this morning 1,370 coins not back too 1,372? This change means a coin was taken off the market or what? Was it a exit scam or something like that?
Can't say for sure. But they have a minimum daily volume threshold ($10,000 I think). I imagine if a coin drops below that threshold for some period of time, it gets removed from the rankings. Not sure, though.
