It was not advisable to keep and invest in Bitcoin alone but to spread our funds. Yet, I put a huge amount into Bitcoin considering its profitability and we know that this project is the most trusted coin in the market where we can assure ROI. And for the huge number of altcoins now in the market, I consider those in the top 10. Maybe I was wrong but I neglect to buy new coins considering scam issues that mostly happen to them. As I bought these coins, I'd never thought about 20-50x, what I just need is to have a favorable profit when the time has come to sell them.
