Right now i am planning to buy btc approx 3-4 btc and just hold them as i guess the price of bitcoin will increase in future and i will get some good profit.But i want to know what is the risk involved.Can bitcoin price decrease and is this right time to buy the bitcoin.
We really can't determine how much risk in bitcoin but I assure you one thing, if you are willing and has the belief with the charts of bitcoin. Then you are not going to talk about the risk instead you are going to compute the possible profit that you may get upon investing there. As long as you did bought bitcoin at lower price, that's good.
If you have bought your bitcoins last year then you have already made huge profits but buying now is a risky as price is already high and we are not sure what will be the price of bitcoins in coming months or years and if we invest in it now and price crashes next year then it will be a huge loss for us.
