Thanks for the advice.
For Beginners this is what I did when I started in 2017.
1. Go through Bitcointalk Forum for best resources.
2. Open up CMC (Coinmarketcap)
3. Of the top 20 coins narrow down to top 10 by going through their website and ANN thread.
4. Join their Telegram Channel and try to understand WHAT THE BUZZ IS ABOUT?
5. Divide your Investment accordingly and Invest majority on the top 2 coins and the rest on the top 8.
6. Enjoy
Thank you Pakhi! That's a general advice we should give to everyone! However, you didn't mention what parameter to use while narrowing down top 10 coins in CMC. You can either narrow down by Market cap, volume or by price! I believe you are talking about market cap and if it's correct then I won't have much to say because market cap is a solid way to look for the strongest top tier currencies and it is also the default view of CMC. However, if you sort the list by price, then you will have a completely new picture in front of you! Just try it yourself and let me know what do you think about them!
Also I would recommend anyone new coming to crypto market, to take time and understand the technology around that crypto first so that they can understand why these cryptos are required for the future and why it will have value! Otherwise it makes no sense for anyone to invest in crytpo just for monetary gain! These group of investors will just end up having debt at the end of the day!
