Investing lots of bitcoin for long term purposes would really pay the price of the waiting time that youve made compare on just holding a little amount , its not worth for the wait . As i mentioned earlier better to hold huge amount so that you could able to feel the profit.
Yes and I think considering the fact that there are hardly any legit and trusted websites that pay good interest left in market, I think the best way is to stock your bitcoins, fix a price in mind which once reached you will sell and just that's it, one thing we all surely know is bitcoins price will increase so make use of it.
