I am starting to consider selling stocks and buying cryptos. Maybe some Steem to improve my position here, and maybe some lightcoin. I don´t feel confindent on how, though. Poloniex? If you have any advice on how to get started, maybe something to read. For example, I don´t know if I will be able to transfer money from my online brokerage account to a place like Poloniex. And I am not sure if I should discuss this with my broker company.
