Jointforce,
Do not buy coins based on Twitter hype. Most likely you're buying the top.
If you want to get in early, here are some tips:
1. Monitor the Altcoin ANN
https://bitcointalk.org/index.php?board=159.0 (eventually you get some real gems)
2. If you're into Pump and dumps, check Altcoin ANN again for possible Pump and dumps. Usually it promises the moon and heavily promoted while disregarding the truth.
3. Join several trading groups in Slack and IRC, so you get a feel of which coin is being accumulated. Take note many are liars and hoodlums.
4. Monitor trollboxes especially C-CEX
5. Consult charts at cryptrader.com and alike, so you know the best price to buy.
Best coin buys are the ones still without hype.
Hyped coins on Twitter, you get a bad risk:reward ratio.
