I dont have access to the slack chat room but i would love to have it.

My first question is: is there a particular currency that is better to trade with? For instance, if i wanted to buy some xmr(just an example), is it better to use ETH, BTC, USDT, LTC?

Is it easier to trade smaller amounts more frequently, or is it ok to buy up a whole bunch of coins at once and then try to unload them all?

Also, everyone talks about "research research research". What are some reputable sources to recieve news about whats going on with the market?
