Investing in BTC is a good idea however, this is not the time of investing in BTC because the price of bitcoin in the market was so high that's why as I advise try to invest in other altcoins and wait to reduce the value of bitcoin in the market.
well if somebody want to increase their money he need to invest in bitcoin and if you think the price is high not suitable for investment, so i think now a days the price of bitcoin is low and it is a good chance to invest your money in bitcoin and i do not think that the price of bitcoin will decrease below this amount, i think it will now in few days start increasing so i will say that it is a good time for investment in bitcoin other than altcoin.
I also think that nowadays the price of bitcoin is lower because in the future the price of it will increase more and more. If anyone will think about that time when the price of bitcoin will be more than $5000 then he will consider the current price a much lower price.
