The best advice I can offer is to buy what you can afford even if small or big. Bitcoin is very volatile over short periods of time but if over 4 years or more it's also volatile but in an upward direction which is good! So if you use the money you don't think you will need for 4 or more years then you should not find yourself in a situation where you have bought too much.
If you find yourself worrying about the price too much and can't sleep it's a sign you are probabaly over invested.
I hope it makes sense. #siamstr
