Ok, so i bought a 100 dollars of bitcoin at coinbase so for the price it was ($4275) when i bought it i got .02239684

so basically if the bitcoin price goes to $8550 i would have an estimate of $200 for the bitcoins i have

so all i have to do is wait till the price goes real high and sell them if i feel like it?

Ok if i buy 100 dollars on bitcoin and in the next days the bitcoin price goes way way down, will i lose my bitcoin can i just leave the bitcoin there for a year and wait till it gets the highest price and sell it?

do you ever lose your bitcoin if they go to low or you can just leave them there forever till they go high o  price?
