- don't put all your buy order at 1place,
- don't buying altcoin in ICO, IPO etc.
- don't buying altcoin when the price rising (+100% or more)
- sometimes we must sell our altcoin, even we lose for buy back at lower rate
- don't buying altcoin with not active dev, potentially scam is higher.
very good set of points for trading. although each of them can be argued and may have exceptions, the general rule for trading is this.
for example sometimes i buy when the altcoin is rising to catch the rocket to the moon and gain at least a portion of the profit, although this is risky i haven't yet striked out.
