THIS IS A QUESTION FOR EXPERIENCED TRADERS IN BITCOIN
I am a novice in BTC but have been lucky so far. I bought BTC at under $2000 and have now sold it at $4100. I am sure that I have made some mistakes in the way that I have bought, stored and sold the BTC.
I now want to trade both long term and short term in BTC. I want to trade in minimum USD $10,000 blocks

Where is the best place to buy BTC using USDs
Where is the best place to store BTC using USDs. As a result of my limited research, security seems to be a major issue. I am prepared to buy a dedicated computer solely to store the BTCs if necessary
What is the best place to Sell BTC using USDs
Saving bitcoins on trading sites is never safe as you never know what will happen to those sites in future as bitfinex scammed many people in the past and ran away with tons of bitcoins of people so its good to buy them and save in offline wallet to keep them safe.
