and also hold some btc for the longterm invesment. I want to sell it if price bitcoin up to $1000
yeah if you're lucky when you're buying at a low price and then prices go up?
I believe everyone is doing in the way of bitcoin investment, because i am also buy the bitcoin when price down and hold it and wait till the bitcoin price high and sometime i hold it for long time, bitcoin is best to get profit in this way, it is really good way to use the bitcoin. Also i don't think that investment need strong strategy.
it's a safe way, but not really a good way. because you just waited too long to make a profit.
better to do it on altcoin, always have a short time to earn huge profits.
