I was wondering if there is a required amount of bitcoins you need to have before you start trading? Also, a little out of topic, but is there a required amount that a person needs to be earning per month before he could start buying bitcoins?
you know it is only depends on you, if you have a .01 you can start but also you should consider the trasaction fees that you will shoulder while doing this, since you also have a other question it seems like you are also trading alts it is also depends on you if you feel that it is enough for you to buy bitcoin with the amount of alts you have maybe 50 to 100 dollars earnings for trading alts it is good enough.
I think nope, there is no high or low amount with which you can start or not but if you have some savings then you can start any time you want with. You can start trading with your desired coin or other source so it is not dependant on low or high amount and sources have no restriction like Bitcoin and other coins are not restricted to buy or a fixed price.
