ICO stage?
From Exchange?
Wait for the dip?
Pre ico will give you big bonus so investing in project during pre ico is good option.
From exchange but when bounty hunters dump tokens and buying on dip is what traders are doing.
Choose strategy which best suits you and you can do all three.
Yes, but buying when pre-ICO must be careful. This can be done in projects that are truly reliable because there are currently many projects that are not useful. The best time to buy is of course when the trend is down or the altcoin market price is low.
