Here this is a big factor of the investment of the money ( whether we are in the cryptocurrency online or in offline in plant project of business individually ) .
Here in my opinion if you are going to invest in the bitcoin then see toward the competeter of the bitcoin also , Because the Market price of any thing depends upon the competition only , Since we are in the cryptocurrency , so here demands matters much then what the another impression these things have .
Here we should make investment in small small steps only , I mean if the market of the bitcoin is much flcutuated then we should buy 100$ - 100$ of btc  only instead to buy all at single time all .
And also we should invest in another coins also like Etherium coin , dash coin , stratis coin , Digibyte coin whichare are available to buy at very low price .
So here my idea of investment is saying that don't go for the investment whole money in the single thing.
