At this time - its not that easy to buy a coin. One need to have a good decent investment and also knowledge to keep a check and balance on the coins.
I think before investing in coins - one should do a through research on what to do and what not to . .
Why not easy to buy?
Buy is always easy, but choosing the right time is a bit complicated.
Buying may seems difficult to him maybe because he doesn't have steady flow of income to buy a coin. That's the challenge most people face who are willing to invest in cryptocurrency, and it is not right to just put in all the savings to start up cryptocurrency investment . Knowledge is important also to make the rightful investment that will yield profits.
Invest on the amount which you can afford to lose which had been the most or primary rule on investment world not only on crypto but also in other investments as well.
