Hello and welcome
Bitcoin talk is a very good place to start indeed
https://bitcointalk.org/index.php?topic=1689727.0There are many good sites to help orient the market. I use
https://coinmarketcap.com/ to look at how the market moves and i like
https://www.coingecko.com/en when i look for a exchange that has a certain coin.
For trading advice and such, I would advice you to look around youtube a bit and this forum, but i can give you some fast tips.
1. Use a liquid exchange, a large one, and trusted is also good. ( Binance, Huobi, Kucoin)
2. Do not enter all at 1 point, this leaves you very vulnerable to market drops, but if you have funds left, a drop will give you a better price average.
3. Avoid news from the world bank and bank of international settlements haha
4. Take profits when you can, all markets have cycles, they go up and down!
5. Be skeptical to technical analyzes and ICO scams, The market is pretty much controlled by emotions as long as the institutional long term investments is lacking. Research ICO´s well, check if the team members Linked in profiles are legit and in the right field of work. Look at the following at twitter and telegram to see how much publicity and hype a certain ICO is getting.
Also think about how large of market an ICO is addressing and how large share it can get, will that bring value to the project? Will it have income? or just be used?
Have fun
