My advice to friends (based on experience)
1.Buy as much as you can
2.Buy on the floor, but do not wait for correction or fall.
3.Do not do anything for the price of tetra and dollars…
4.If it comes down to a short time that you bought at a reasonable price….
5.If it comes down in the long run and stays that you did not lose in the long run, everything will be cheaper than the dollar.
6.Do not act emotionally… Wherever you say to buy or sell… you are more likely to lose
If you have any suggestions, let us all know so we can use this experience.
Thanks

the first point is heretical advice. buying as much as you can using all your money is stupid. it is a high risk. Better to set aside some money to buy bitcoins and do it more often as long-term savings.
