first of all try to learn the basics of trading/investing;
you can google for books for more indepth look at the topic,
try tons of free articles available all over the internet (like the ones on
investopedia.com)
and look at numerous threads available on this forum. (mostly located in
trading discussion.)
decide wether you wanna trade bitcoin and fiat or bitcoin and altcoins.
look up a number exchanges on
service announcements.
check them out personally to see which interface you prefer.
read about people's opinions on them in
service discussion.
establish your trading plan.
move a little bit funds to your balance in your favorite exchange and start testing the water.
dont confuse yourself with many different coins and options;
you'll need to spend time to keep track how their markets move and react in different conditions.
if you find an interesting coin, study it in depth and familiarize yourself with its dev team and community.
initially try older more stable coins with big market caps.
have discipline, once you did spend time to develop a plan
stick to it.
have tenacity, remember failures always happen and
don't quit.
