What would be a good exchange to start trading ? coinsecure or something else ?
what is "pump and dump" ?
Also what does HODL mean ? These might all be very common but am just learning...with a little help will soon get up to speed
* coinsecure is really good. You could try pocketbits.in[1] as well. Pocketbits.in is open 24x7 and has fast KYC procedure to get you going. Currently KYC with coinsecure is loaded thus you may face delay of some days or some weeks depending on load at coinsecure. So for quick start check pocketbits along with coinsecure. BTXindia and localbitcoins[2] as well.

* pump and dump is a phenomenon commonly observed in stock, bitcoin exchange, where big players with load of financial strength create artificial hike in price. Once other people starts to purchase on large scale they simply dump their holdings and earn huge profit. This causes sudden drop in price. Any unjustified rise in price is potential sign of 'pump and dump' scenario.
* HODL is bitcoin lingo which means don't sell your bitcoins for short term gain. Instead hold them for longer for bigger returns.
pocketbits.in is a new exchange and they aren't active on forums too. I would suggest not to go for it.
Go for coinsecure.in or unocoin.com(if coinsecure is too overwhelming for you) they might take longer to get you verified but that ain't too bad.
Also have a look at cryptowat.ch, it list all major international crypto exchanges.
