Risk management 101 in crypto:
1) Never invest too much amount that cause you lose sleep when things going south.
2) Be sure to take profit of your initial capital.
3) Never assume but verify and DYOR, it is what you think you know but ain't true that will fuck you over.
@CryptoSays Just to give an alternative viewpoint.
Not everyone here comes from a high income country.
For low income countries, $33 can be a weekly or even a monthly salary. Price is simply relative to income, spending patterns and personal values.
