With the high price of Bitcoin, I think its unwise to invest your money in bitcoin at this point in time. Maybe it's better to look for other Altcoins being offered in the Market. What do you think?
If bitcoin price is not affordable to buy, then as you say buying altcoins that are more affordable is a good option to invest. Although altcoin does have a cheap price but the future of its development is easier to estimate. So the profits that we will get will be bigger as long as we diligently check the price and the latest info about altcoin.
