I invested $85 into ethereum yesterday and after couple hours I lost $10 ,,,does it mean it's not the best time to invest yet and secondly I'll like to ask if that amount is good enough to invest in such a stable coin
Hmm, most advices here are assuming that cryptocurrencies are going to "skyrocket" or "moon" in the future. Which shouldn't be the sole main reason you "invested" in crypto, or ETH in your case.
For me, I "invested" monetarily in crypto via mining (a.k.a. securing the network) and staking, because I strongly believe that Crypto and Blockchains are here to stay and will be the "Internet Boom" for Currencies in human history. By mining and staking, I actually contributed to the whole network model and helped in the experiments run by all these different crypto foundations and organizations. The coin rewards from mining and staking are part of the "bonus" along the way
So ask yourself, whats the primary reason for your investment. If its for the x100 gain for price difference, you will have to prep yourself with the mindset that any coin can potentially drop to pennies. Also do extensive background research on a coin before investing, and determine yourself whats the strong point of the coin that you investing, be it the team behind it, the technology behind it etc.
At the end of the day, invest only what you can afford to lose.
