10x profit is something which may happen once or twice in decade. Maybe it happens in this crypto space more frequently but only whales could cover them as there are 1000s of altcoins and only 1% of them are having potential to grow 10 times in short period; if you miss the timing then investing those 1% of coin also will be meaningless.

But, bitcoin is known for getting us 10x profits every 4 years. I have been watching it since 2013. If bitcoin gets into 200k region this year, then my speculation on bitcoin for 10x profits every four years will be accurate one.

You must focus on long term holding which is the only strategy you must learn and practice. For long holding, only highly reputed coins like bitcoin and ethereum are good so do not risk on random coins.
