Yes in 2017 price was so high and before that price was low so it is so normal to see price increasing so if for some time it is down then it does not matter allot. Long ago investing in 2017 must given you power to hold because only holding Has the ability to make you earn all that money you have mentioned
Would like to remember last 2017 the best shot for crypto life ever. That is pretty amazing, but sadly it came into the point that the market turning back into 1 year of crisis and Bitcoin still did well and even survive from a long bearish season. The price is very cheap at that time, imagine if we buy a lot of BTC's last year, we double or make it triple in today's price.
I would like to return the time and go to 2017 when I was in the bullish phase, where not only was it earned in bitcoin, but that any project had an incredible success rate, however I think that due to this stage in which we are, it is not very far from reliving it, due to my way of seeing the market we are at the beginning of the bullish phase, there may be some kind of re-accumulation, but it is very difficult, given that there are external factors that are influencing the crypto world .
The mere fact that they are about to launch in 2020 Libra, has awakened alarms worldwide, even strong countries like China, are already thinking about launching their cryptocurrencies, despite all this, it is positive, because it makes Bitcoin start to have many more market participants, new investors, more bitcoin purchases, and the fact that bitcoin has a finite or limited number of Bitcoin causes demand to start increasing and supply to decrease, this is achieved over time and only So the price of Bitcoin will continue to rise.
