Market fluctuation are always used by the whale investors. It's nothing more than their earning strategy. They buy quick making the market go up and sell quick to dump it to novice and small investors to let the market fall and again buy the coins for cheap. So, small investors should be aware of what is happening with their investment.
My tips at current time.
1. If you are in larger loss, hold, the coin would rise one day.
2. If you are in small loss or profit, hold or sell, wait the market to stabilize a bit and buy.
3. If you haven't invested yet, don't jump in now, let the market stabilize before buying.
I agreed holding would be the best choice for those who already got stucked with some of these altcoins and im sure if you did your own research before investing to these shitcoins you would not be worried because if you have solid coins,it will surely recover in no time.For those who are planning to invest in cryptocurency market you just need to wait for some breakouts,wait for the total marketcap to stabilize so it will be safe for you to jump in.Some of the people are surely taking the advantages of the cheap altcoins today,that might be a good idea because if the market recovered in just few weeks surely you are making a lot of money in that time.
Most traders have surely taken advantage of the red market that we are experiencing right now. Despite the market crashing and being unstable, it's a great time to start investing or buying in coins when the price is low as it is right now. Buying coins at a low price will give you huge profits once the coin's price will start to climb in the future.
Holding is definitely best for those whose investments are now down in the dumps, because what goes down will always go up and the market will always recover after some time.
