For now, I would advise you to buy bitcoin. the current price is very low is a very good thing for you to buy. the influence of bitcoin is very large on the market and this is certainly a good thing for investment
Those who invested in the coins few months ago when the price was 8k have lost values. These who did the same in the last month of 2017 have lost more than 80% values and the tourists are leaving the industry for they can not hold any longer. But the new guys can enter and invest for benefits.
