Price is going higher and higher in recent times and we may see the same trend in coming months so I think buying them now and holding them for a long term is the best and safest way to make profits as we may see ATH in coming months.
yes currently it is really a good way of making money, specially right now when the price of bitcoin is continuously increasing and it is expected that the price will very soon reach to a very very high price. may be this time cross 1500 USD. so investment at this stage will be a good decision.
