Rates are going to get higher because getting entry into cryptocurrencies are getting harder and harder. Many of my social friends that are getting into crypto now are asking people to sell them because they cannot buy using coinbase or related places. This is a sign that cryptocurrencies can get more and more valuable for this 1 factor.
Pal, as mentioned earlier, you do not have to buy a whole coin. put whatever you can in and repeat. Don't listen to your social friends and certainly do not sell now. There are so many options to buy now it is insane, so many exchanges and platforms! Try not to look at the price daily, it can be quite nauseating but just remeber the lower the price it means bitcoin is on sale and you will get more for your money in the long run!
