Cmon. Such words are true for small business. They have a goal to catch a profit and run away. To be honest, my buy/sell in BTC were about +50 - +200 percent, and i never was 100% right when decided to buy and to sell.
Today i think that BTC can`t give you x10 or more, just be happy to get 10-20%.
But old holders today get x100-x1000. But i`m sure that we willn`t know their names.
Even 20% gain over a year is already massive in investment world.
Apparently if you see current BTC growth, it did more than 5 times already from lowest price at bearish and up until now.
Since BTC is projected to reach 1 million anyway, I'm sure it can still do 10x in the future. Just matter of whether you have the patience to wait and whether you have diamond hands.
